The AmScope PM200T common main objective (CMO) trinocular stereo zoom microscope has a pair of 10x extreme-widefield eyepieces, a 0.8x-5x zoom objective, and track stand. The common main objective (CMO) has an infinity optical system that provides higher resolution and increased light-gathering capability over traditional optics. The microscope has an overall magnification range of 8x-50x. The trinocular viewing head has an adjustable interpupillary distance, a 20-degree inclination to reduce eye and neck strain, and 360-degree rotation to enable sharing. The trinocular port can be used as a C-Mount or 23mm photo port (camera sold separately). The WF10x22mm extreme-widefield eyepieces combine with the 0.8x-5x 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. 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. The upper LED ring light provides shadow-free illumination, and can be removed to provide access to the objectives. 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. Both lights have a rheostat to control the amount of light emanating from the lamp. The pillar-style stand has bilateral coarse focus and fine to ease use for left- and right-handed users. All metal construction is durable and the enamel finish is stain-resistant. The microscope is 19-1/2 x 9-1/2 x 14-3/8 inches/50 x 24 x 37mm (H x W x D, where H is height, the vertical distance from the lowest to highest point; W is width, the horizontal distance from left to right; D is depth, the horizontal distance from front to back), and has a 110V-240V auto-detecting power supply.

Microscopes are instruments used to enhance the resolution of an object or image. Types include compound, stereo, or digital. Compound microscopes use a compound optical system with an objective lens and an eyepiece. Stereo microscopes show object depth in a three-dimensional image. Digital microscopes are used to display an image on a monitor, rather than looking through a lens. Microscopes can have monocular (one), binocular (two), or trinocular (three) eyepieces, with varying magnification abilities. Magnification ability refers to the size of an image. Resolution, also known as resolvant power, refers to the clarity of the image. The interaction between field of view (FOV), numerical aperture (NA), and working distance (WD) determines resolution. Microscopes can control magnification through a fixed focus, or through a range of adjustments. They can also utilize LED, fluorescent, and mirror light sources to help control viewing capabilities. Microscopes are widely used in education, lab research, biology, metallurgy, engineering, chemistry, manufacturing, and in the medical, forensic science, and veterinary industries.
