The AmScope SH-2BZ-C2 professional stereo zoom microscope has interchangeable pairs of 5x, 10x and 20x widefield eyepieces, a 1x-4x zoom objective, and a pillar stand. The microscope has an overall magnification range of 5x-80x. The binocular viewing head has an interpupillary range of 55 to 75mm, a 45-degree inclination to reduce eye and neck strain, and 360-degree rotation to enable sharing. The WF5x18mm, WF10x18mm and WF20x10mm widefield eyepieces combine with the 1x-4x zoom objective to provide continuous zoom magnification and a longer working distance for inspecting large-scale specimens that require handling or repair. Dioptric adjustment accommodates individual eye-strength differences. The microscope includes a 0.5x Barlow lens that can be added to the objective to decrease the magnification range. A Barlow lens with a magnification of less than 1.0 reduces magnification and increases the working distance. A stereo microscope, sometimes called an inspection or dissection microscope, has low magnification and a long working distance that enables users to manipulate the object being inspected.

The microscope has upper (episcopic) illumination that reflects light off the specimen for enhanced visibility of opaque specimens, and lower (diascopic) illumination that transmits light up through the specimen for enhanced visibility of translucent and transparent objects. A frosted stage plate allows light to pass through from below with transparent specimens, a reversible black and white stage plate provides contrast with light- and dark-colored specimens, and stage clips secure the specimen during viewing. The 10W halogen light source provides bright light in a concentrated path, and a rheostat controls the amount of light emanating from the lamp. The pillar-style stand has bilateral coarse focus to ease use for left- and right-handed users, and stage clips to secure the specimen during viewing. All metal construction is durable and the
