The microscope has lower (transmitteddiascopic) Brightfield illumination that transmits light up through the specimen for enhanced visibility of translucent and transparent objects. Brightfield (BF) illumination allows the specimen to absorb lightresulting in a dark image on a light background. Halogen illumination provides bright light in a concentrated path and has a rheostat to control light intensity. The 1.25 NA Abbe condenser is mounted on a rack-and-pinion control systemcan be adjusted to control the distance of the light from the stageand has an iris diaphragm to optimize the amount of light illuminating the specimen. The double-layer mechanical stagewith 1mm stage divisionslocks the slide into place and provides precise slide manipulation along the X- and Y-axis to allow coordinates to be recordedenabling the viewer to return to a specific location on the slide. A stage stop prevents the stage from coming into contact with the slide and objectives. The stage is 5-1/2 x 5-1/2 inches (140 x 140mm) and has a traveling range of 2-15/16 x 1-3/4 inches (75 x 45mm). Graduated coaxial coarse and fine focus has a focusing range of 1-3/16" (30mm) and fine-focus divisions of 0.002mm (0.0000787") that enable measurements to be taken. Focus knob tension control prevents the stage from drifting out of focus. The solid-metal enamel-coated body is durable and resistant to stains and corrosion.

Specifications

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 magnification abilities. 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 utilize LEDfluorescentand mirror light sources to help control viewing capabilities. Microscopes are widely used in educationlab researchbiologymetallurgyengineeringchemistrymanufacturingand in the medicalforensic scienceand veterinary industries.

United Scope manufactures microscopy equipment and accessories under the brand name AmScope. The companyfounded in 1996is headquartered in IrvineCA.
