The AmScope M135C2LPB10 monocular compound microscope has 10x widefield and 25x widefield eyepieces, a reversemounted nosepiece with three DIN achromatic objectives, Brightfield upper and lower LED illumination, a 0.65 NA singlelens condenser, and a plain stage. The reversemounted revolving nosepiece has 4x, 10x, and 40x DIN achromatic objectives that provide color correction of magnified images. The monocular viewing head holds the WF10x or WF25x eyepiece on a fixed 45degree vertical inclination to reduce eye and neck strain and has 360degree rotation capability to provide a more comprehensive view and enable sharing. A compound microscope is used for inspection and dissection of specimens when twodimensional images are desired.The microscope has upper (episcopic) LED illumination that reflects light off the specimen for enhanced visibility of opaque specimens, and lower (diascopic) LED illumination that transmits light up through the specimen for enhanced visibility of translucent and transparent objects. Brightfield (BF) illumination allows the specimen to absorb light, resulting in a dark image on a light background. LED illumination provides bright, cool light for working with temperaturesensitive or live specimens. The 0.65 NA singlelens condenser and disc diaphragm control the amount of light illuminating the specimen. The plain stage has an opening for light transmission and stage clips to secure the slide or specimen in place while viewing. A stage stop prevents the stage or specimen from coming into contact with the objectives. The microscope has two AA rechargeable batteries and a power adapter to allow use away from power sources. The solidmetal frame has a stainresistant enamel finish for durability. The microscope comes with five blank slides and five prepared slides.

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 threedimensional 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. Whats in the Box?
