• Professional stereo micro with pillar stand has long working distance to enable users to perform work or manipulate large items, including circuit boards and dental appliances.
• Trinocular viewing head with pair of 10x super-widefield eyepieces, adjustable interpupillary distance, fixed 45-degree vertical inclination to reduce eye and neck strain, and 360-degree rotation capability to enable sharing.
• 0.7x-4.5x zoom objective provides continuous zoom magnification and longer focal length for inspecting large-scale specimens.
• Rheostat-controlled upper and lower LED light provides intensity control and bright, cool light for working with temperature-sensitive or live specimens, frosted stage plate allows light to pass through from below with transparent specimens, and reversible black and white stage plate provides contrast with light- and dark-colored specimens.
• Pillar-style table stand with bilateral coarse focus and stage clips to secure the specimen during viewing.

The Am SM-2T-LED professional trinocular stereo zoom micro has a pair of 10x super-widefield high-eyepoint eyepieces, a 0.7x-4.5x zoom objective, and a pillar stand. The micro has an overall magnification range of 7x-45x. 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- or 23mm photo port (camera sold separately). The WH10x20mm 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. High-eyepoint eyepieces ease viewing for users who wear glasses, and dioptric adjustment accommodates individual eye-strength differences. A stereo micro, sometimes called an inspection or dissection micro, has low magnification and a long working distance that enables users to manipulate the object being inspected. The micro 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 a of light emanating from the lamp. The pillar-style stand has bilateral coarse focus to ease use for left- and right-handed users. All metal construction is durable and the enamel finish is stain-resistant.

Types include compound, stereo, or digital. Compound micros use a compound optical system with an objective lens and an eyepiece. Stereo micros show object depth in a three-dimensional image. Digital micros are used to display an image on a monitor, rather than looking through a lens. Micros 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. Micros 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. Micros are widely used in education, lab research, biology, metallurgy, engineering, chemistry, manufacturing, and in the medical, forensic science, and veterinary industries. United manufactures microscopy equipment and accessories under the brand name Am. The company, founded in 1996, is headquartered in Irvine, CA.
