The AmScope SM-5TZZ-FOR professional trinocular stereo zoom microscope has a pair of 10x and 20x super-widefield high-eyepoint eyepieces, a 0.7x-4.5x zoom objective, two Barlow lenses, and a ball-bearing controlled double-arm boom stand. The microscope has an overall magnification range of 3.5x-180x. 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 WH10x20mm and WH20x10mm super-widefield high-eyepoint eyepieces combine with the 0.7x-4.5x zoom objective to provide continuous 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 fiber-optic ring light has a 150W/21V cool-light halogen light source for observing temperature-sensitive specimens. The ring light provides shadow-free illumination, and a rheostat controls the amount of light emanating from the lamp. The ring light has a 2-1/8" (56mm) inner diameter, a 3-1/8" (80mm) outer diameter, and a 35" (890mm) metal-sheathed light cable. Power and adjustment controls are located on a control box to speed adjustments. The light source
