AmScope 10X20X Kids Battery Powered Binocular Stereo Dissecting Microscope with LED Light

The AmScope SE100X-LED elementary stereo microscope has interchangeable pairs of 5x18mm and 10x18mm widefield eyepiece, a 2x objective, LED 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 interchangeable pairs of WF5x and WF10x eyepieces combine with the 2x objective to provide 10X or 20x magnification and a longer working distance for inspecting large-scale specimens that require handling or repair. A stereo microscope, sometimes called an inspection or dissection microscope, has low magnification and a long working distance that enables users to manipulate the object being inspected. Upper (episcopic) 1W LED light reflects light off the specimen. An LED light source provides bright, cool light for working with temperature-sensitive or live specimens. The light is powered by two AA batteries (included), enabling the microscope to be used 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 secure the specimen during viewing. The microscope has a 2-3/4" (70mm) working distance. All metal construction is durable and stain-resistant.

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, rather than looking 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, 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. Microscopes 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. 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. What's in the Box?
