Zeiss SteREO Discovery V20 Microscope

Stereo Discovery V20 2020

The SteREO Discovery V20 microscope is a Carl Zeiss stereomicroscope with its motorized zoom in range of 20:1. It is equipped with a motorized focus controller and a tall arm, allowing for the placement of very large specimens on the base. With a Zeiss Axiocam 820 color camera, the Zeiss Zen software, associated with the microscope, allows the documentation of settings while images are taken. The software also facilitates the acquisition of z-stack images which can be computed in the software to an extended focus image allowing you to view your entire specimen in a greater depth of field.
