Kern OZL 465 Stereo Zoom Microscope, 7x-45x Zoom, LED Reflected and Transmitted Light
Whether you’re checking a printed circuit board for soldering faults or preparing an insect for a biology lesson, you need an image with depth of field and the ability to switch quickly between an overview and close-up detail. The Kern OZL 465 stereo zoom microscope covers a zoom range of 0.7x to 4.5x; with the supplied 10x eyepieces, this gives a total magnification of 7x to 45x. The binocular head sits on a column stand, is tilted at 45 degrees and can be rotated through 360 degrees. LED lighting illuminates the specimen either from above or from below, with separate dimming controls. Kern positions this model as an all-rounder for schools, training centres, testing facilities and laboratories. Zoom range and field of view The zoom lens covers a range from 0.7x to 4.5x, a ratio of 6.4 to 1. When used with the HWF 10x eyepieces, this results in the stated total magnification of 7x to 45x. At the lower end of the zoom range, the field of view is 28.6 mm; at the upper end, it is 4.4 mm. This allows an entire circuit board to fit within the field of view, or a single solder joint to be viewed in close-up. The working distance of 105 mm leaves enough space for tweezers or a soldering iron beneath the optics, whilst the stage accommodates samples up to 140 mm in height. Head and stand adjusted to the user The dioptre adjustment operates on both sides from minus 5 to plus 5, whilst the interpupillary distance can be set between 55 and 75 mm. High-eye-point eyepieces ensure the distance between the eyes and the lens is sufficient for spectacle wearers. The microscope head is detachable; the head mount has a diameter of 76 mm and therefore also fits other modular Kern stands. Focusing is achieved via a coarse focus knob; the OZL 465 does not have a separate fine focus knob. LED illumination for reflected and transmitted light Incident and transmitted light can be dimmed separately, each with 3-watt LED output. Incident light illuminates opaque specimens such as printed circuit boards, minerals or insects from above, whilst transmitted light illuminates thin specimens and microscope slides from below. The contrast mode is brightfield. The presence of two independently controllable light sources in a single unit distinguishes the OZL 465 from simpler stereo microscopes with only one direction of illumination. Digitisation: optical in the basic model, expandable via accessories The basic model of the OZL 465 does not have a built-in camera sensor; it is a purely optical microscope. Users who wish to display or document the specimen on a screen can retrofit the microscope with an eyepiece camera. For users who require a digital image from the outset, Kern offers the OZL 462, a dedicated microscope head with a digital output. This is a standalone product with its own item number and is not part of this offer. Storage and warranty The housing can withstand storage temperatures ranging from minus 5 to 40 degrees Celsius, which is relevant for transport in winter or for temporary storage in an unheated adjoining room. Kern provides a 36-month warranty on the device and confirms, in accordance with REACH classification, that it contains no prohibited substances. Typical applications Kern cites a wide range of applications for the OZL-46 series, from reproductive medicine to quality control: In-vitro fertilisation Parasite detection Zoology and botany Tissue preparation and sections Quality control Specimens with a three-dimensional appearance, such as insects, seeds, printed circuit boards or components In educational settings, the microscope displays specimens from biology lessons in three dimensions rather than as flat images. In electronics manufacturing, quality assurance uses it to check solder joints and assembled printed circuit boards for completeness, without having to set up a digital system for every production run. Frequently asked questions about the OZL 465 Can a camera be fitted at a later date? Not as a retrofit directly onto the OZL 465, but an eyepiece camera can be added as an accessory. For a unit with a factory-fitted digital output, the separate OZL 462 head is the right choice. How tall can the sample be? The stage accommodates samples up to 140 mm in height. Is the microscope suitable for people who wear spectacles? Yes, the eyepieces are designed with a high eye point, and the dioptre adjustment ranges from minus 5 to plus 5 on both sides. How heavy is the microscope? The net weight is 4.6 kg, and the dimensions are 300 x 240 x 420 mm. Is transmitted light possible for thin specimens? Yes, transmitted light can be dimmed independently of the incident light; both light sources are LED-based. What type of plug is supplied? The mains adaptor comes with a EURO plug; other versions for the UK, US or Switzerland are available as options according to the data sheet.

Kern OIV 345 Digital Video Microscope, 11.6-inch HD Display (PC-free), TOIV 345-B
Anyone who needs to examine a sample under a microscope whilst documenting it at the same time will be familiar with the bottleneck between the eyepiece and the computer. The Kern OIV 345 video microscope solves this by combining the optics, camera and an 11.6-inch HD display in a single unit. The image appears directly on the built-in screen, without the need for a computer, software installation or eyepiece. Display and image capture without a PC The 11.6-inch LCD display with tempered glass measures 275 x 170 x 12 mm, displays the camera image at 1920 x 1080 pixels (HD) and can be tilted between 0 and 45 degrees, ensuring a comfortable viewing angle at the workstation regardless of the operator’s height. The built-in 5-megapixel camera with a Sony CMOS sensor (1/2.8-inch) delivers a smooth live image at up to 60 frames per second, captured using a rolling shutter. The device is operated directly via the display using the supplied wireless USB mouse; a separate keyboard or computer is not required for day-to-day use. Recordings can be saved either to the supplied 32 GB USB stick or to a microSD card, again without the need for a computer. If you wish to display the image on a larger screen, for example, in a training session or when evaluating a sample as a team, you can connect the OIV 345 to an external monitor or projector via HDMI. Only for the advanced S-VIEWER software, with its additional measurement and evaluation functions, does a separate PC need to be connected via USB 2.0. For this, Kern recommends at least an Intel Core i3 or AMD Ryzen 5, 8 GB RAM, a 128 GB SSD, a graphics card in the class of an NVIDIA RTX 3060 or AMD Radeon RX 6600, and a Full HD screen of at least 20.5 inches. Click-stop zoom for reproducible magnification The optical zoom covers 0.7x to 4.5x directly at the sensor, giving a zoom ratio of 6.4:1. The display’s scaling factor of 22.8 results in a total magnification of 15.96x to 102.6x. The zoom wheel locks into defined click-stop positions, making it easier to recall a setting once it has been found for the next sample, for example when a series of similar components is inspected one after the other at the same magnification. A fixed 0.5x objective and the absence of an eyepiece keep the optical design simple: the system is axially aligned, meaning that the illumination and camera are positioned on the same axis as the sample, without any lateral offset. Illumination and working area The LED ring light is positioned as an incident light around the optics and can be dimmed continuously, from low background illumination to bright light for shiny or dark surfaces. It has a power output of 3 watts, and the contrast mode is bright-field. The working distance is 100 mm; samples up to 110 mm in height fit beneath the objective lens, such as smaller assemblies or workpieces that do not need to be dismantled first. The mechanical stand has a column height of 330 mm and supports the head, optics and display as a single unit. Power supply, dimensions and buffer cell Measuring 320 x 260 x 450 mm (W x D x H) and weighing 4.4 kg net, the unit stands securely on the laboratory bench without the need to allow for additional space for a separate monitor. The desktop power supply can be disconnected from the unit and covers an input range of 100 to 240 V AC at 50 or 60 Hz; the unit itself is supplied with 12 V at 2,000 mA, and the connection cable is 2.5 m long. This means the OIV 345 operates on virtually any standard mains supply, even outside Germany. The permissible storage temperature ranges from -5 to 40 °C. The housing also contains a very small lithium buffer cell with a lithium content of 2 mg and a capacity of 0.018 Wh. It has passed the UN38.3 transport test, which applies to the shipment of devices containing built-in lithium cells, including by air freight. Menu languages and S-VIEWER software The user interface is available in seven languages: German, English, French, Italian, Russian, Japanese and Chinese. The S-VIEWER software (Kern OXM 904) is also available for analysis on a PC. It covers image processing, video recording, documentation and measurement functions, in other words, precisely the steps that follow after simply viewing the results on the device, when a result is to be included in a test report or a quality assurance file. Anyone wishing to integrate the OIV 345 into an existing documentation system can export the images via a USB stick or MicroSD card and open them in the software on an office PC. Typical applications In quality control, a team can jointly inspect a solder joint or the edge of a component on the display, without having to take turns looking through the eyepiece. In electronics and semiconductor manufacturing, the axial optics assist in inspecting fine structures on circuit boards and components. In education and training, several people can view the same image simultaneously, which simplifies working with microscopes that have a single eyepiece. In mineralogy and tissue preparation, the instrument aids the visual assessment of samples; in materials testing, it facilitates the inspection of surfaces and fracture edges; and in parasite detection, it enables the examination of relevant specimens. Quality control Materials testing Electronics and semiconductor industry Education and training Research Mineralogy Tissue preparation Parasite detection Frequently Asked Questions Can the OIV 345 be used without a PC? Yes. Imaging, zooming and saving are controlled via the integrated 11.6-inch display and the USB mouse supplied; a computer is not required for operation. A PC is only required if you wish to use the S-VIEWER software. What is the magnification of the device? Optically at the sensor: 0.7x to 4.5x. When displayed on the screen with a scaling factor of 22.8, this equates to 15.96x to 102.6x. What is the camera’s resolution? 5 megapixels via a 1/2.8-inch Sony CMOS sensor, at up to 60 frames per second. Where are images and videos stored? Externally via USB, on the supplied 32 GB USB stick or on a microSD card. What interfaces does the OIV 345 have? Two USB 2.0 ports, an HDMI output for an external monitor and a microSD card slot. How high can samples be? Up to 110 mm below the lens, at a working distance of 100 mm. In which languages can the menu be operated? German, English, French, Italian, Russian, Japanese and Chinese. How long is the warranty valid for? 36 months. Does it contain a battery that is relevant for shipping? Yes, a small lithium backup cell containing 2 mg of lithium, which has passed the transport test in accordance with UN38.3. Does the device bear the CE mark? Yes, and according to the manufacturer, it contains no substances prohibited under REACH.

Kern OBN 135 Transmitted Light Microscope, Trinocular, 4x-100x, Köhler
A trinocular transmitted-light microscope with Köhler illumination is the instrument of choice for anything that goes beyond simply viewing a specimen, from blood smears in haematology to sediments in water analysis. The Kern OBN 135 transmitted-light microscope, with five Infinity-Plan objectives, covers a magnification range from 4x to 100x, whilst the Köhler illumination ensures an evenly illuminated image area across the entire field of view. The third eyepiece port makes the microscope ready for a camera, even though none is supplied with the basic model. Five objectives, ranging from low magnification to oil immersion The revolver houses five Infinity-Plan objectives: 4x/0.11, 10x/0.25, 20x/0.45, 40x/0.65 and 100x/1.25 in oil immersion. The three higher-magnification objectives are spring-loaded and spring back if accidentally placed on the slide, rather than damaging the lens or specimen. All five feature an anti-fungal coating, which is important in humid laboratory environments. Five objectives in five revolver positions mean there is no wasted space and every magnification level is immediately available. Trinocular head and ergonomics The Siedentopf tube is inclined at 30 degrees and can be rotated through 360 degrees. The dioptre adjustment operates on both sides from minus 5 to plus 5, whilst the interpupillary distance can be adjusted between 50 and 75 mm. The HWF-10x eyepieces, with a 20 mm field of view, also feature an anti-fungal coating and are designed as high-eye-point eyepieces. The tube diameter of the eyepieces is 23.2 mm, the standard DIN specification for this component. Köhler illumination and Abbe condenser The LED transmitted light illumination operates according to the Köhler principle and is infinitely variable, with a colour temperature of 6,000 Kelvin and a power output of 3 watts. The Abbe condenser is centring and height-adjustable, with an aperture of 1.25. In the manufacturer’s description, Kern refers to this combination as professional-grade equipment for demanding applications. Depending on the objective, the field of view ranges from 0.2 mm to 5 mm. Cross-table and fine adjustment The large mechanical cross-table features a coaxial coarse and fine adjustment mechanism that can be operated from either side. The fine adjustment mechanism operates with a minimum step of 0.002 mm; at 100x magnification in oil immersion, this is the difference between a sharp and an out-of-focus image. Camera retrofit: C-mount required separately The trinocular tube has a third port for a camera, but no sensor is fitted in the basic model. A C-mount adapter is required for the camera connection; this is not included in the Scope of delivery and must be ordered separately. Standalone microscope or digital microscope kit: correctly classifying the OBN 135 Kern sells several versions under the model designation OBN 135. This product, listed as lt-22616 at LT Laborhandel, is the standard optical microscope without a camera. In addition, Kern offers digital microscope kits fitted with a camera as standard, such as the model OBN 135T241. At LT Laborhandel, this set is listed as a separate product: the Kern digital microscope set OBN 135T241, with the product number lt-22619. Those who wish to document digitally from the outset, without having to assemble a C-mount adapter and camera themselves, are better served by this set. Those who look exclusively through the eyepiece or wish to choose their own camera at a later date should opt for the OBN 135 described here. Contrast techniques beyond the basic configuration By default, the OBN 135 operates in brightfield mode. Darkfield, polarisation, fluorescence and phase contrast are available as additional contrast techniques, each requiring supplementary accessories. This is relevant for laboratories which, in addition to routine stained specimens, occasionally examine unstained or birefringent samples, for example in microbiology or materials science. Typical applications Kern cites a wide range of applications for the OBN 13 series, spanning laboratory medicine and industry: Haematology Urology Gynaecology Dermatology Pathology Microbiology and Parasitology Immunology Sewage treatment works Oncology Entomology Veterinary practices Water analysis Breweries Inpatient facilities Clinical laboratories Public health authorities Training centres Universities At a public health authority, a technician uses it to test drinking water samples for bacteria; at a veterinary practice, a faecal smear is examined for parasite eggs. At universities and training centres, the same instrument serves as an introduction to microscopy, using the same optics that students will later use in their professional careers. Frequently asked questions about the OBN 135 What is the difference between the OBN 135 and the OBN 135T241 set? The OBN 135 is purely optical, whilst the OBN 135T241 set (LT Laborhandel item no. lt-22619) comes with a factory-fitted camera. Is a camera included in the Scope of delivery? No, the trinocular tube is prepared for a camera; a C-mount adapter must be ordered separately. What is the maximum magnification? 100x with the oil immersion objective, numerical aperture 1.25. Can I use phase contrast or polarisation? Yes, as optional contrast techniques via accessories; the basic model is preset to brightfield. How finely can the focus be adjusted? The fine-adjustment knob operates with a minimum increment of 0.002 mm. What is the eyepiece size of the microscope? 23.2 mm tube diameter, which is the standard DIN specification for microscope eyepieces. How heavy is the instrument? The net weight is 10 kg, and the dimensions are 390 x 200 x 395 mm.

KERN OPO 185 Polarising Microscope, transmitted and reflected light, infinity
KERN OPO 185: The flexible, high-end polarising microscope for professionals The KERN OPO 185 (MPN OPO 185) is the flagship model of the Professional Line POL. It has been specially developed for demanding analyses of materials with optical anisotropy, such as those encountered in mineralogy, petrography, crystallography and materials testing. This instrument impresses with its enormous flexibility: it combines powerful LED reflected and transmitted light illumination with high-quality infinity optics. Whether transparent thin sections or opaque ores – the OPO 185 delivers razor-sharp, high-contrast images. Maximum power: 5W LED & 5-position objective turret Unlike basic models, the OPO 185 features two extremely bright 5-watt LED illuminators. Reflected light: Ideal for opaque specimens. Transmitted light: For classic transparent specimens. Both units are infinitely dimmable and ensure long-lasting, colour-faithful illumination (Köhler illumination in transmitted light with an adjustable Abbe condenser 0.9/0.13 ‘Swing Out’). The 5-position objective turret is fitted with five specialised, tension-free Infinity Plan objectives (4x, 10x, 20x, 40x, 50x), which cover an enormous magnification range. Fully equipped for polarisation analysis The KERN OPO 185 leaves nothing to be desired when it comes to crystal optical examinations: Bertrand lens: Permanently integrated and focusable for konoscopy (observation of axial images). Compensators: A complete set of sliders (lambda, lambda/4, quartz wedge) is included to determine phase differences. Precision stage: The large specimen stage is mounted on ball bearings, rotates through 360° and features 1° graduations as well as 6' fine graduations with a locking function. Trinocular tube for documentation The Siedentopf tube is trinocular. This means you can observe comfortably with both eyes (30° viewing angle, dioptre adjustment on both sides) whilst simultaneously connecting a microscope camera via the third optical path. This makes the OPO 185 the perfect workstation for laboratories that produce reports or conduct training sessions. Areas of application Geology & Mineralogy: Identification of mineral phases and rock structures. Industry: Analysis of stress cracks in glass or plastics (stress optics).

KERN OKM 173 Metallurgical Microscope, reflected light, trinocular, infinite-corrected optics
Geometric Optics of Metallurgical Reflected-Light Microscopy In materials science fractography, metallurgical quality control and the examination of opaque (light-impermeable) semiconductor structures, conventional transmitted-light microscopes fail due to the total physical absorption of photons within the solid. The KERN OKM 173 is designed as a high-precision metallurgical epi-illumination microscope. In this complex optical setup, the objective lens also functions as a condenser. The integrated 30-watt halogen light source emits a continuous, broadband spectrum of photons. This light is precisely directed into the optical axis via a partially transparent beam splitter in the microscope stand, focused onto the sample through the objective lens and reflected by the metallic solid-state surface. The reflected light passes through the objective lens once more and produces, in the trinocular tube, an image of the microscopic grain structures, voids or microcracks that is exceptionally high-contrast and free of artefacts. Physical superiority of the infinity-corrected optical path The metrological heart of the OKM 173 is its infinity-corrected optical system (Infinity Optics). In contrast to finite optical systems with a fixed tube length (e.g. 160 mm), with infinity optics the light rays emerge from the objective as parallel beams. Only a specially calculated tube lens in the microscope head focuses these parallel photons into a real intermediate image. This physical space occupied by the parallel rays between the objective and the tube lens is of essential importance: it allows additional optical components – such as polarising filters, analysers or DIC prisms – to be introduced without causing a shift in the optical focal length, spherical aberrations (aberrations) or microscopic ghost images. Polarisation optics and anisotropy analysis Particularly with reflective metallic surfaces or polished micrographs, unpolarised halogen light often leads to severe flare, which masks the finest phase boundaries in the metal lattice. The OKM 173 is therefore equipped as standard with a high-performance polarisation and analyser unit. The polariser forces the transverse electromagnetic light waves into a defined plane of oscillation. Reflection off the anisotropic crystal structure of the metal sample specifically alters the polarisation state of the light. The downstream analyser physically blocks out interfering specular reflections and makes optical stress-induced birefringence, grain boundaries and heterogeneous alloy phases visible with maximum microscopic contrast. Planachromatic optics and digital image conversion To reproduce the absolutely flat polished surfaces typical of metallurgy without geometric errors, the system is equipped with planachromatic objectives. These highly complex lens systems correct chromatic aberration for two spectral colours and physically flatten the image field so that both the centre and the extreme peripheral areas of the solid-state sample are simultaneously in absolutely sharp focus. The trinocular Siedentopf tube also enables simultaneous binocular visual inspection by the user and the loss-free coupling of the photon flux to a digital microscope camera (C-mount). This is essential for comprehensive digital documentation and software-based metrology in certified laboratories. Technical details Optical system: Infinity-corrected (Infinity Optics) Microscope type: Metallurgical epi-illumination microscope Tubus design: Trinocular (Siedentopf), 30° inclination, 360° rotatable Illumination type: 30 W halogen epi-illumination (continuously dimmable) Optical path: Partially transparent mirror for coaxial illumination Objectives: Planachromatic LWD (Long Working Distance) optics Standard magnifications: 5x, 10x, 20x, 50x (plan objectives) Eyepieces: HWF 10x / Ø 18 mm (with dioptre adjustment on both tubes) Optical contrast enhancement: Includes polariser and analyser unit Mechanical cross-table: Large surface area (approx. 200 x 150 mm) for solid workpieces Focusing: Coaxial coarse and fine adjustment with mechanical stop Camera output: C-mount adapter for digital image capture Power supply: Integrated mains power supply (230 V) Scope of delivery 1 x KERN OKM 173 metallurgical microscope (stand and tube) 4 x Planachromatic LWD objectives (5x, 10x, 20x, 50x) 2 x HWF 10x wide-field eyepieces 1 x polarisation and analyser unit 1 x 30-watt halogen replacement bulb 1 x C-mount camera adapter 1 x dust cover and mains cable 1 x Detailed operating instructions Individual requirements & accessories The trinocular optical path of the OKM 173 is mechanically and optically designed to accommodate a high-resolution digital microscope camera (e.g. KERN ODC series with CMOS sensor). To carry out metrological length or angle measurements on metal structures via the software, such a camera, in conjunction with an object micrometre for calibration, is essential. For analyses requiring extremely high magnification, the system can also be upgraded with a plan-achromatic 100x LWD objective.

Kern OZL 463 Stereo Zoom Microscope, Binocular, 0.7x-4.5x, LED Reflected and Transmitted Light
Anyone working on circuit boards, components or small workpieces who simply wants to assess the result with the naked eye does not need a microscope with a camera output. The Kern OZL 463 from the OZL 46 series is designed for just that: a binocular stereo zoom microscope with a zoom range of 0.7x to 4.5x, LED reflected light and LED transmitted light on a column stand. With the standard 10x eyepieces, this gives a total magnification of 7x to 45x.Optics and field of viewThe optical system is a Greenough system, producing a three-dimensional image. The field of view has a diameter of 28.6 mm at the lowest magnification and is still 4.4 mm at 4.5x. The working distance is 105 mm; specimens may be up to 140 mm high. Kern specifies a maximum resolution of 0.0037 mm. The HWF 10x eyepieces have a 20 mm field of view and a high eye point. The tube is inclined at 45 degrees and can be rotated; the interpupillary distance ranges from 55 to 75 mm, and the dioptre adjustment operates on both sides. Focusing is achieved via a coarse focus knob.Illumination and standThe microscope features reflected light and transmitted light, each with a 3-watt LED. Both light sources can be dimmed independently, allowing dark circuit boards to be illuminated from above and transmitted-light specimens from below as required. The column stand has a base area of 290 x 240 mm, whilst the head mount has a diameter of 76 mm. Kern points out that the head is detachable from the stand and can be integrated into other modular systems, such as a universal stand. The power supply is built-in (100 to 240 V, detachable power cable, protection class I).Which OZL is suitableThree Stereo Zoom models from our range are very similar.OZL 463 (this model)Binocular, 0.7x to 4.5x, working distance 105 mm, specimen height 140 mm, 4.2 kgOZL 466Trinocular, 0.7x to 4.5x, working distance 105 mm, specimen height 140 mm, 4.6 kgOZL 456Binocular, 0.75x to 5x, working distance 113 mm, specimen height 45 mm, 4.6 kgThe difference compared to the OZL 466 is the third tube outlet for a camera.

Kern OZL 466 Stereo Zoom Microscope, Trinocular, 0.7x-4.5x, LED Reflected and Transmitted Light
The Kern OZL 466 is a trinocular stereo zoom microscope on a column stand, designed for specimens with spatial depth, such as circuit boards or components. The zoom is continuously adjustable from 0.7x to 4.5x; with the 10x eyepieces, this results in a total magnification of 7x to 45x. Reflected light and transmitted light are provided by two separately dimmable LED sources, and the third tube outlet accommodates a camera.Zoom wheel with detents and field of viewThe zoom wheel has an integrated click-stop mechanism. It locks into defined magnification steps so that a setting selected once can be reproduced for the next specimen. The zoom range corresponds to a ratio of 6.4:1. The field of view measures 28.6 mm in diameter at the lowest magnification and shrinks to 4.4 mm at 4.5x. Kern specifies a maximum resolution of 0.0037 mm. The working distance is 105 mm; samples may be up to 140 mm high, meaning that even a populated circuit board or a larger workpiece will still fit beneath the head. The optical system is a Greenough system with two separate beam paths; the image is three-dimensional.Eyepiece side and adjustmentThe tube is inclined at 45 degrees and can be rotated. The interpupillary distance can be adjusted from 55 to 75 mm, and the dioptre adjustment operates on both sides. HWF 10x eyepieces with a 20 mm field of view and high eye point are fitted as standard in the tube, so spectacle wearers can view the image even whilst wearing spectacles. Kern offers accessories including 15x, 20x and 25x eyepieces, as well as a 10x eyepiece with a scale (0.1 mm). Focus is adjusted via a coarse focus knob.Camera operation with a 50:50 optical pathThe optical path is split 50:50 between the eyepieces and the camera output. Kern cites this as suitable for documentation, live image transmission and precise inspection and soldering work. Users who wish to assess the image through the eyepiece whilst simultaneously capturing it do not need to switch between the two operating modes. C-mount adaptors with 1x, 0.3x and 0.5x magnification are available for connection, as well as an eyepiece adaptor for microscope cameras. Suitable cameras from Kern include the ODC 825, ODC 832, ODC 852, ODC 874 and ODC 881 models. Those who wish to view images, take measurements and save data on a tablet can use the ODC 241 tablet camera. We stock the ready-assembled set with the tablet camera as the OZL 464T241.Column stand, lighting and powerThe base of the column stand measures 290 x 240 mm, whilst the holder for the microscope head has a diameter of 76 mm. Kern points out that the head can be removed from the stand and integrated into other modular systems, such as a universal stand. The reflected light and transmitted light sources each have a power of 3 watts; both sources can be dimmed separately. Stand inserts in frosted glass and black and white, each 95 mm in diameter, are included. The power supply is built-in; the input voltage is 100 to 240 V, and the unit is connected via a detachable power cable (Protection Class I).OZL 466 or OZL 463The OZL 463 has the same optics, the same lighting and the same column stand, but features a binocular head without a camera output and weighs 4.2 kg instead of 4.6 kg. Anyone who is certain they will not be connecting a camera will find the OZL 463 sufficient. If you wish to document images or cannot yet rule out the possibility of doing so, choose the OZL 466.Typical applicationsKern cites schools, training centres and workshops, testing centres and laboratories, as well as assembly and repair workstations, for example, in the electronics industry, as typical applications for the OZL 46 series.Training in schools and training workshopsAssembly and repair workstationsElectronics industryTest centres and laboratoriesSoldering work and inspection using a cameraFrequently asked questionsWhat is the magnification of the OZL 466?

Kern OCM 168 Inverted Microscope, Trinocular, 5 W LED for Reflected and Transmitted Light, Long Working Distance
Cell cultures grow in dishes and plates, and anyone wishing to examine them needs space for the culture vessel above the objective lens. The Kern OCM 168 is an inverted microscope designed for this purpose: the objectives are positioned beneath the stage, the specimen rests on top, and, according to Kern, the working distance is very large. Kern describes the instrument as an inverted biological laboratory microscope with fluorescence capability. It features a trinocular head, Infinity-Plan objectives at 10x, 20x and 40x, a PH 20x phase-contrast objective, as well as LED transmitted light and LED reflected light of 5 watts each.Equipment for culture monitoringThe mechanical stage travels 128 mm in one direction and 180 mm in the other. It is fitted with a specimen holder for Ø 110 mm. A holder for 54 mm culture dishes is included in the Scope of delivery; holders for 35 and 65 mm dishes are available from Kern as accessories. The Abbe condenser has an aperture of 0.3, an aperture diaphragm and a working distance of 72 mm. Kern specifies it for brightfield, phase contrast and fluorescence applications. A phase contrast slider, centring eyepiece and green filter are included as standard.LightingThe transmitted light source is a 5 W LED and is dimmable; the incident light source is a second 5 W LED for epi-illumination. Power is supplied via a plug-in power supply unit rated at 100 to 240 V, 50/60 Hz and 0.3 A (Protection Class III); the connection cable is detachable. The OCM 168 is constructed in the same way as the OCM 167, but features a fluorescence filter unit for UV, V, B and G instead of just B and G, and weighs 17 kg instead of 16 kg.Head and eyepiecesThe eyepieces are HWF 10x with a 22 mm field of view, anti-fungal coating and high eye point. The Siedentopf tube is trinocular and inclined at 45 degrees; the interpupillary distance can be adjusted from 48 to 76 mm, and dioptre adjustment is available on both sides.

KERN OBE 132 Transmitted-light microscope, trinocular, 40x–1000x, 3W LED, achromatic
The modern all-rounder for training and everyday laboratory use The KERN OBE 132 sets new standards in the category of robust educational microscopes. As a trinocular variant of the popular OBE-1 series, this transmitted-light microscope has been specially designed for use in secondary schools, vocational colleges and training centres, as well as for routine laboratory applications. It combines an exclusive, dynamic design with the durability and ergonomics that are essential for daily, intensive use. For anyone looking for a reliable instrument that not only delivers brilliant images but also offers the option of digital documentation, the OBE 132 is the perfect choice. Trinocular tube: Ready for the digital world The standout feature of the OBE 132 is its trinocular microscope head. In addition to the two eyepieces for stereoscopic viewing, this model features a third, vertical optical path. This allows for the permanent connection of a microscope camera (C-mount adapter available separately). This is of inestimable value, particularly in teaching or training: the live image can be transmitted to a monitor, projector or PC, enabling an entire group to view and discuss the specimen at the same time. Documenting findings or creating training materials thus becomes child’s play. The tube itself is designed as an innovative ‘butterfly’ tube. This not only allows for quick adjustment of the interpupillary distance but also ensures an ideal viewing angle (30° tilt), which effectively prevents neck pain during prolonged use. The head can also be rotated through 360°. High-performance optics and illumination The KERN OBE 132 is equipped with four high-quality, achromatic objectives (4x, 10x, 40x and 100x). In combination with the HWF 10x/18 mm wide-field eyepieces, you can achieve a magnification range from 40x to 1000x. The 100x objective is designed for oil immersion (immersion oil required), enabling the observation of the finest structures, such as bacteria or details in blood smears. To prevent damage, both the 40x and 100x objectives are mounted on spring-loaded mounts. Illumination is provided by a modern, high-performance 3W LED. This ensures excellent, bright illumination of the specimen at a colour temperature similar to daylight. A key advantage of LED technology over halogen lamps is its long service life and the absence of heat generation – your samples are not ‘cooked’, which is particularly important when examining living organisms. The brightness is, of course, infinitely adjustable. Precise mechanics and well-designed features The full-featured mechanical cross-table ensures the precise positioning of your specimens. Using the ergonomically positioned, coaxial control knobs (for the x and y axes), you can move the specimen with millimetre precision without having to take your eyes off the eyepieces. Focusing is also achieved via a coaxial coarse and fine focus control on both sides, which allows for rapid yet highly precise focusing. Beneath the stage is a height-adjustable Abbe condenser (N.A. 1.25) with an iris diaphragm. This allows you to optimise the light path using Köhler illumination (within a fixed frame) and to perfectly adjust the contrast to the specimen in question. Another practical feature for everyday laboratory use: a large storage compartment is integrated into the rear of the unit. The mains cable can be stowed away quickly and securely here after use – this keeps the cabinet tidy and prevents cable tangles during transport.

KERN OBT 106 School Microscope, monocular, 40x–400x, LED transmitted light, battery-powered
The ideal introduction to microscopy: the KERN OBT 106 for schools and training The KERN OBT 106 is a high-quality school microscope that has been specially developed for modern biology lessons in primary and secondary schools, as well as for ambitious hobbyists. As part of the tried-and-tested OBT 1 series from KERN Optics, it combines intuitive operation with robust mechanics and optical performance that will inspire pupils’ lasting enthusiasm for the microcosm. Unlike simple toy microscopes, this is a fully-fledged optical instrument manufactured to the standards of professional laboratory microscopes, yet perfectly tailored in terms of function and ergonomics to the needs of beginners. Brilliant optics for fascinating insights At the heart of the KERN OBT 106 lies the achromatic optical system. Equipped with three high-quality objectives (4x, 10x and 40x) and a 10x wide-field eyepiece, the microscope covers a magnification range from 40x to 400x. This range is regarded as the ‘gold standard’ for school teaching. It enables detailed observation of classic specimens: from the structure of an onion skin cell to the leg hairs of a housefly, right through to the fascinating organisms found in pond water (paramecia, rotifers). The 40x objective is spring-mounted (retractable). This is a crucial safety feature in school settings: should the stage be raised too high by accident, the spring-mounted front lens gives way. This effectively prevents damage to the expensive specimen or the front lens of the objective – a common problem with inexperienced users, which has been resolved through the design of this instrument. Ergonomics and handling in the classroom The OBT 106’s tube is monocular and tilted at an ergonomic viewing angle of 45°. This allows for a relaxed posture even during longer observation sessions. A particular advantage for group work: the microscope head can be rotated a full 360°. This means the microscope can simply be turned on the table to show the adjusted image to a neighbouring student or the teacher, without having to move the entire stand. This prevents the specimen from slipping and promotes collaborative learning. Focusing is achieved via a coaxial drive on both sides for coarse and fine adjustment. This arrangement, in which the coarse and fine drives are aligned on a single axis, is intuitive to use and allows the focal plane to be located quickly, as well as enabling precise refocusing at high magnifications. The fixed stage (110 x 100 mm) is fitted with two robust specimen clamps that securely hold the slide in place. Innovative LED illumination and portable use A highlight of the KERN OBT 106 is its modern 1W LED illumination. Compared with conventional halogen lamps, LED technology offers significant advantages for school use: the light is bright white and colour-accurate, which makes it easier to identify cell structures. Furthermore, it generates almost no heat, meaning that living specimens (e.g. aquatic organisms) do not dry out or die. The lighting is infinitely dimmable, allowing the brightness to be optimally adjusted to suit the specimen in question. Image quality is enhanced by a condenser (N.A. 0.65) fitted beneath the table, featuring a rotatable pinhole disc. Simply turning the disc significantly increases the contrast, which leads to a real ‘aha moment’, particularly with transparent or unstained specimens. For maximum flexibility in the classroom or on field trips, the OBT 106 is equipped with rechargeable batteries. It can therefore be operated independently of the mains supply, thereby avoiding the risk of tripping over cables in the classroom.

Kern OCM 166 Inverted Microscope, Trinocular, Halogen Transmitted Light and 100 W HBO Reflected Light, 10x-40x
The Kern OCM 166 is one of the HBO variants in the inverse OCM series, featuring fluorescence filters for UV, V, B and G. A 30-watt halogen lamp provides the brightfield illumination for transmitted light, whilst a 100-watt HBO lamp, which powers the epi-fluorescence unit, provides the reflected light. Kern describes the instrument as an inverted biological laboratory microscope with fluorescence. The head is trinocular; the objectives are Infinity-Plan objectives with 10x, 20x and 40x magnifications, plus a PH 20x phase-contrast objective.Two light sources for two techniquesThe halogen lamp illuminates the specimen from above in brightfield mode and is adjustable. The 100-W HBO lamp from Osram is housed in the epi-fluorescence incident light unit and excites fluorescent specimens from below through the objective. Kern describes the Abbe condenser with an aperture of 0.3 and an aperture diaphragm as suitable for brightfield, phase contrast and fluorescence applications; its working distance is 72 mm. For the halogen light, Kern supplies a 6 V/30 W replacement bulb (OBB-A1372) as an accessory.Inverted configuration for culture vesselsAs the objectives are positioned beneath the stage, the specimen remains accessible from above.

KERN OLM 170 Metallurgical Inversion Microscope, Reflected Light, LED, Trinocular
Inverse geometry for bulk solid-state analysis In industrial materials testing, semiconductor inspection and foundry analysis, heavy, large-volume or asymmetrical samples present conventional upright microscope systems with insurmountable mechanical challenges. The KERN OLM 170 eliminates these limiting spatial constraints through its inverse (reversed) system architecture. The plan-achromatic objectives and the focusing mechanism are physically positioned beneath the large cross-table. This allows solid engine blocks, thick steel slabs or heavy printed circuit boards to be placed directly on the table without any height restrictions. In terms of process engineering, this reduces the preparation effort enormously: the workpiece need only be ground and polished to be absolutely flat on the underside to be examined under the microscope. The need for time-consuming plane-parallel alignment of the entire sample body with the optical axis is physically eliminated entirely. Optoelectronics of the LED reflected-light illumination In stark contrast to systems using thermal halogen lamps, the OLM 170 is based on state-of-the-art semiconductor physics. The system is equipped with a high-performance, coaxial 5-watt LED incident light source. The light-emitting diode emits a high-intensity, completely flicker-free and colour-neutral photon spectrum with an extremely low heat output. This cold light source prevents the thermal expansion of the microscope’s mechanical components (thermospatial drift) and protects heat-sensitive semiconductor wafers from thermomechanical stress. The coaxial incident light is precisely directed into the optical axis via a partially transparent beam splitter, passes through the objective as a condenser and is reflected directly into the tube system by the opaque metal surface. Physical precision of the infinity optics The metrological foundation of the OLM 170 is its infinity-corrected lens system (Infinity Optics). The light waves reflected by the solid-state sample leave the objective as parallel beams. Only a tube lens incorporated into the trinocular microscope head focuses these photons into a sharp, real intermediate image. The physical space occupied by the parallel radiation between the objective and the tube lens enables the distortion- and aberration-free integration of optical accessories, such as the supplied polarisation and analyser unit. The system remains completely free from induced chromatic aberrations or shifts in focal length. Anisotropy detection and digital metrology When observing highly polished metal sections under reflected light, directional light inevitably leads to severe reflections (glare). The OLM 170 overcomes this phenomenon with its integrated polarisation system. The polariser forces the light waves into a linear plane of oscillation, whilst the crossed analyser physically blocks diffuse specular reflections. This maximises phase contrast and makes stress-induced birefringence, microcracks and heterogeneous alloy boundaries visible. To document these structures metrologically, the microscope features a trinocular tube with a C-mount adapter pre-fitted at the rear. This enables the direct, co-axial attachment of a digital microscope camera, whilst an internal light splitter (20:80) allows simultaneous inspection through the eyepiece.

To measure lengths, areas or angles in your polished surface photographs with pixel-level precision, we recommend combining it with a calibrated digital microscope camera (e.g. the KERN ODC series) and a suitable object micrometer.

KERN OLM 171 Metallurgical Inversion Microscope, Reflected Light, Trinocular
Inverse geometry for solid materials In industrial fractography, castings inspection and metallurgical quality assurance, conventional upright microscopes immediately reach their mechanical limits when examining solid workpieces. The fundamental technical advantage of the KERN OLM 171 is its inverse (reversed) design. The objectives and the focusing mechanism are physically located beneath the solid cross-table. This design architecture completely eliminates height restrictions for the sample material. Heavy engine components, solid steel slabs or thick semiconductor wafers can be placed directly on the table. Another decisive preparative advantage: with an inverted microscope, the workpiece need only be ground and polished to be absolutely flat on the underside to be examined. The time-consuming process of aligning the entire sample geometry to be plane-parallel – which is absolutely essential with upright systems – is completely eliminated. Physical superiority of infinity optics The metrological heart of the OLM 171 is its infinity-corrected optical system (Infinity Optics). The stream of photons reflected from the sample surface emerges from the objective as a parallel beam and is only focused into a real image by a specially calculated tube lens. This parallel beam path (infinity space) is fundamental to high-precision microscopy: it allows the stress- and aberration-free integration of additional optical modules, such as the polarisation and analyser unit included in the system, without shifting the optical focal length or inducing chromatic aberrations. High-performance incident light and anisotropy analysis Opaque (light-impermeable) metallic structures require a high coaxial photon density to resolve microscopic grain structures or crack edges (voids). The system is equipped with an extremely powerful 50-watt halogen epi-illumination system. To physically block the glare that inevitably occurs with reflective metal sections, the polariser is swivelled into the beam path, forcing the transverse light waves into a defined plane of vibration. Reflection off the crystal structure of the metal sample alters this state of polarisation. The analyser filters out diffuse specular reflections and makes optical stress-induced birefringence as well as heterogeneous alloy phases visible with maximum phase contrast. Planachromatic LWD optics and metrological documentation To image the flat polished surfaces typical of metallurgy without geometric distortion, the microscope is equipped with planachromatic LWD (Long Working Distance) objectives. These highly complex lens systems flatten the field of view, ensuring that both the centre and the peripheral areas of the solid workpiece are simultaneously in absolute focus. In addition to binocular visual inspection, the trinocular tube enables the simultaneous, loss-free coupling of the optical signal to a digital C-mount microscope camera. This is essential for the seamless measurement of grain sizes and software-based documentation in the field of quality management.
