The YM-S20 elementary stereo microscope has a pair of 10x widefield eyepieces, a 2x objective, tungsten lighting, and a reversible black and 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 WF10x18mm eyepieces combine with the 2x objective to provide 20x magnification and a longer working distance for inspecting large-scale specimens that require handling or repair. A stereo microscope, often referred to as an inspection or dissection microscope, 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 microscope for use away from wired power sources. 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 protected the specimen all over viewing. The microscope has a 2-3/4″ (۷۰mm) working distance. All metal construction is durable and stain-resistant.

Microscopes are instruments used to improve 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, moderately than taking a look 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, often referred to 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 regulate magnification through a fixed focus, or through a range of adjustments. They are able to also utilize LED, fluorescent, and mirror light sources to help regulate viewing capabilities. Microscopes are widely used in education, lab research, biology, metallurgy, engineering, chemistry, manufacturing, and in the medical, forensic science, and veterinary industries.
United Scope manufactures microscopy equipment and accessories under the brand name AmScope. The company, founded in 1996, is headquartered in Irvine, CA.
