This microscope features a durable cast aluminum body with enamel finish and a safety rack stop to prevent objective lens damage. An 88 x 82mm plain stage moves up and down. Locked-on clips hold a specimen in placeand one or more high-position focus control knobs make visual adjustments. Coarse focus moves the objective lenses toward or away from the specimen. Fine focus precisely tunes the focus on all or part of the specimen. Illumination shines light up from below the stage through the specimen. Models with LED and incandescent illumination use 110V AC and come with a US/North American plug. LED illumination is energy-efficient and provides cool illumination equal to a 20-watt tungsten bulb. Tungsten incandescent illumination is bright but also produces heatand is not recommended for viewing live cultures or specimens. Mirror illumination directs ambient light up through the hole in the stage and requires no external power. A disc diaphragm varies the amount of light passing through the stage opening to properly illuminate the specimen and increase contrast and resolution. The microscope comes completely assembled with a clear vinyl dust cover and instructions.

Microscopes are instruments used to enhance the resolution of an object or image. Types include compoundstereoor 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 monitorrather than looking through a lens. Microscopes can have monocular (one)binocular (two)or trinocular (three) eyepieceswith varying viewing abilities. A trinocular eyepiece is used to output digital images or video to an internal or external device such as a camera or monitor. Magnification ability refers to the size of an image. Resolutionalso known as resolvant powerrefers 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 focusor through a range of adjustments. They can also use LEDfluorescentand mirror light sources to help control viewing capabilities. Microscopes are widely used in educationlab researchbiologymetallurgyengineeringchemistrymanufacturingand in the medicalforensic scienceand veterinary industries.
