• LED illumination powered by 2AA batteries.
• Great for viewing insects, s, rocks, stamps, coins, fabrics, fingerprints, electronic circuit boards and more.
• 5 year warranty.

The Am SE100ZZ elementary stereo micro has interchangeable pairs of 10x18mm and 25x9mm widefield eyepiece, a 2x objective, tungsten lighting, and a white stage plate. The binocular viewing head has an interpupillary range of 55 to 75mm and a fixed upright inclination to simplify viewing for young users. The interchangeable pairs of WF10x18mm and WF25x9mm eyepieces combine with the 2x objective to provide 20X or 50x magnification and a longer working distance for inspecting large-scale specimens that require handling or repair. 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. Upper (episcopic) 3W tungsten light reflects light off the specimen. A tungsten (incandescent) light source provides bright light. The light is powered by two AA batteries (included), enabling the micro to be used away from wired power sources. Bilateral coarse focus eases use for left- and right-handed users. The stage has a 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 2-3/4" (70mm) 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.
