Kern OZL 468 stereo zoom microscope, trinocular, 0.7x to 4.5x, LED incident and transmitted light

The Kern OZL-46 series comprises six stereo zoom microscopes with LED incident light and LED transmitted light for assembly and repair workstations, training workshops and testing centres. The zoom range is continuously adjustable from 0.7x to 4.5x; when used with the HWF 10x eyepieces, this provides a total magnification of 7x to 45x. Three models are binocular (OZL 463, OZL 465, OZL 467), and three are trinocular with a third port for a camera (OZL 464, OZL 466, OZL 468). All models have a built-in power supply.

Which model

The binocular models OZL 463, OZL 465 and OZL 467 do not have a camera output. The OZL 463 and OZL 465 are mounted on a column stand; according to the data sheet, they differ in net weight (4.2 kg versus 4.6 kg). According to the data sheet, the OZL 467 has a mechanical stand. Of the trinocular models, the OZL 464 and OZL 466 have a beam splitter ratio of 50:50, meaning that the eyepieces and camera can be used simultaneously. Both are mounted on a column stand and feature a click-stop on the zoom wheel. For the OZL 468, the beam splitter ratio is 0:100 according to the data sheet, and the stand is mechanical, as stated in the data sheet. If you need to document and observe live through the eyepiece at the same time, choose the OZL 464 or the OZL 466. Those who work exclusively at the eyepiece will find the OZL 463, the OZL 465 or the OZL 467 sufficient.

Zoom, field of view and click-stop

According to the data sheet, the zoom wheel on the OZL 464 and OZL 466 has an integrated click-stop. It clicks into defined magnification steps so that a setting, once selected, can be found again reproducibly. The data sheet does not specify a click-stop for the other models. The zoom ratio is 6.4:1. The field of view measures 4.4 to 28.6 mm, the working distance is 105 mm, and the maximum specimen height is 140 mm. The Greenough system provides a stereoscopic image. The tube is inclined at 45° and rotates through 360°; the interpupillary distance ranges from 55 to 75 mm, and the dioptre adjustment operates on both sides from -5 to +5. The HWF 10x eyepieces have a 20 mm field of view, a high eye point and a 30 mm mounting diameter, and are fixed in the tube.

Illumination and camera connection

The incident and transmitted light sources are 3 W LEDs, each of which can be dimmed independently. The contrast method is bright field. A C-Mount adapter is required to connect a camera. Kern lists the microscope camera adapters OZB-A4809 (1x), OZB-A4810 (0.3x) and OZB-A4811 (0.5x), as well as the eyepiece camera adapter OZB-A4863 (1x). For models with a camera output, Kern lists the ODC 241, ODC 825, ODC 832 and ODC 852 cameras. For the OZL 464 and OZL 468, the ODC 854 is added; for the OZL 468, so is the ODC 251.

Stand, power and dimensions

According to the brochure, the stand allows the microscope head to be removed and fitted into other modular systems, such as a universal stand. The coarse focus mechanism features torque control. The power supply is built-in and operates at 100 to 240 V; it is connected via a power cable. The microscopes measure 300 x 240 x 420 mm. The OZL 463 and OZL 464 have a net weight of approx. 4.2 kg, while the OZL 465, OZL 466, OZL 467 and OZL 468 weigh approximately 4.6 kg.
