AmScope Kids SE100ZZ-LED Portable LED Stereo Microscope with 20X and 50X Magnifications

The AmScope SE100ZZ elementary stereo microscope 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 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) 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 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 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?AmScope SE100ZZ stereo microscopeWF10x18mm eyepieces, 23mm, one pairWF25x9mm eyepieces, 23mm, one pairWhite stage plateTungsten bulb, 3W(2) Stage clips(2) AA batteriesDust coverInstructions (by download)
