The Barska 20x, 40x Binocular Stereo Microscope is constructed with 2 separate light paths which result in a true stereo or three dimensional (3-D) image of the specimen. Within the objective lens of this microscope you will find two lenses, one for each path of light, side-by-side. The optical design parameters of a stereo microscope limit its 3-D effects to low powers only.
This type of microscope features a large stage for closer viewing of the non-microscope world. Items such as insect parts, plant and flower parts, fossils, stamps, coins, PC boards, material surfaces, etc. does not need to be mounted on a slide. For comfort, this microscope has an adjustable interpupiliary distance between 55mm ~ 75mm.
