• 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.
• Binocular 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, and a 0.5x Barlow lens extends the working distance.
• Removable rheostat-controlled 64-bulb LED ring light provides intensity control and bright, cool light for working with temperature-sensitive or live specimens.
• Pillar-style table stand has reversible black and white stage plate to provide contrast with light- and dark-colored specimens, and large stage clips to secure the specimen during viewing.

The Am SM-1BSX-64S professional stereo zoom micro has a pair of 10x super-widefield high eyepoint eyepieces, a 0.7x-4.5x zoom objective, a 0.5x Barlow lens, and a pillar stand. The micro has an overall magnification range of 3.5x-45x. 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 WH10x20mm super-widefield high-eyepoint eyepieces combine with the 0.7x-4.5x zoom objective to provide 7x-45x continuous zoom magnification and a longer working distance for inspecting large-scale specimens that require handling or repair. High-eyepoint objectives ease viewing for users who wear glasses, and dioptric adjustment accommodates individual eye-strength differences. The micro includes a 0.5x Barlow lens that can be added to the objective to decrease the magnification to 3.5x-22.5x. A Barlow lens with a magnification of less than 1.0 reduces magnification and increases the working distance. 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 removable 64-bulb LED ring light provides bright, cool light for working with temperature-sensitive or live specimens. The ring light provides shadow-free illumination, and a rheostat controls the a of light emanating from the lamp. Power and adjustment controls are located on the light head. The light uses a 110V-240V variable power supply. The table stand has a reversible black and white stage plate that provides contrast with light- and dark-colored specimens, and stage clips to secure the specimen in place. The stage plate has a 3-3/4" diameter (95mm). The stand is 10 x 7-7/8 x 10-3/4 inches/254 x 200 x 275mm (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).

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.
