Barska Trinocular Stereo Microscope 20x, 40x

The Barska 20x-40x Binocular Stereo Microscope is a fixed power stereo microscope with 20x, and 40x magnifications. This model of binocular microscope also has a third optical channel with a monocular eyepiece port. This allows a second person (e.g. a teacher) to view the same specimen that the first person is observing via the binocular optics. This microscope by Barska is constructed with two separate light paths which results in a true stereo, or three dimensional (3D) image of the specimen. Within the objective lens of this Barska Microscope, 2 lenses (one for each path of light) are found side-by-side. The optical design parameters of a stereo microscope limit its 3-D effects to low powers only.
