The AmScope ZM-2TZ professional trinocular stereo zoom microscope has a pair of 10x extreme-widefield high-eyepoint eyepieces, a 0.67x-4.5x zoom objective, two Barlow lenses, and a pillar stand. The microscope has an overall magnification range of 3.35x-90x. The trinocular 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 vertical trinocular port can be used as a C-Mount or 23mm photo port (camera sold separately). The EW10x22mm extreme-widefield high-eyepoint eyepieces combine with the 0.67x-4.5x zoom objective to provide zoom magnification and a longer working distance for inspecting large-scale specimens that require handling or repair. The microscope comes with 0.5x and 2.0x Barlow lenses that can be added to the objective to increase the magnification range. A Barlow lens with a magnification of less than 1.0 reduces magnification and increases the working distance, while a Barlow lens with a magnification greater than 1.0 increases the magnification and reduces the working distance. High-eyepoint eyepieces ease viewing for users who wear glasses, and dioptric adjustment accommodates individual eye-strength differences. 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.
