The AmScope M30-ABS-KT2-W beginner compound microscope has a monocular viewing head with LED and mirror illumination, a built-in color-filter wheel, a forward-facing rotating turret with 300x, 600x, and 1200x magnification, and a white metal frame. The monocular viewing head has LED and mirror illumination and a built-in color-filter wheel for viewing a variety of specimen types. Coaxial coarse focus eases use for young users and has a rack-and-pinion focus mechanism for precise focusing. The plain stage has stage clips that secure the slide or specimen in place during viewing. The white metal frame is durable and stain-resistant. The microscope comes with a 52-piece accessory kit with brine shrimp eggs and hatchery, and a hard-sided plastic carrying case. The LED light is powered by two AA batteries (included).

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?
