• Elementary stereo micro for home or classroom use enables students and hobbyists to inspect biological specimens, rocks, stamps, jewelry, and large specimens that require handing or manipulation.
• Binocular viewing head with interchangeable pairs of 5x and 10x widefield eyepieces, adjustable interpupillary distance, and 45-degree inclination to simplify viewing for young users.
• 2x objective provides low magnification and longer focal length for inspecting large-scale specimens.
• Ambient lighting illuminates the specimen, eliminating the need for power or batteries.
• Reversible black and white stage plate provides contrast with light- and dark-colored specimens, and stage clips secure the specimen.

The Am SE204-AX elementary stereo micro has interchangeable pairs of 5x18mm and 10x18mm widefield eyepieces, a 2x objective, ambient lighting, and a reversible black and white stage plate. The binocular viewing head has an interpupillary range of 55 to 75mm and a 45-degree inclination to ease viewing for young users. The WF5x18mm and WF10x18mm eyepieces combine with the 2x objective to provide 10x and 20x magnification and a longer working distance for inspecting large-scale specimens that require handling or repair. The optical glass lenses provide sharp images, and are fully-coated to ensure high-resolution images. Dioptric adjustment accommodates individual eye-strength differences, and eye guards ensure comfortable viewing. 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. Ambient lighting illuminates the specimen, eliminating the need for power or batteries. Bilateral coarse focus eases use for left- and right-handed users. The stage has a reversible black and white stage plate that provides contrast with light- and dark-colored specimens, and stage clips that secure the specimen during viewing. The micro has a 3-3/16" (81mm) working distance. All metal construction is durable and 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.
