The Konus Crystal-Pro Microscope is a low-to-medium magnification stereoscopic binocular with a zoom objective and a special mounting stand. Its geared mounting stand and arm allow you to place the binocular microscope directly above a three-dimensional subject placed on the table.
As a trinocular microscope, the Crystal's 3rd optical path is typically used for photomicrography or for displaying the image live to a screen for teaching purposes.
The T-shaped vertical and lateral geared movement of the special mounting arm, combined with the zoom objective lens, allows the Crystal-Pro to easily swing around and get above specimens in a jiffy. This is an ideal microscope for observing things like rocks, vegetables, bugs, etc. - any time you've got a collection of things that vary in size and shape and want to observe all of them quickly, the Crystal-Pro's a perfect fit.
The Crystal-Pro does not come with any illumination, but there are both incident and direct illumination sources available.
