The Frey Scientific compact fixed-magnification stereo microscope is used for inspection and dissection, creates three-dimensional images, has straight binocular viewing heads, 10X widefield eyepieces, 20X or 30X fixed magnification, 10W three-way tungsten incandescent illumination, and a durable cast aluminum body with enamel finish. Microscopes are widely used in education, lab research, biology, metallurgy, engineering, chemistry, manufacturing, and in the medical, forensic science, and veterinary industries.
This microscope features straight binocular viewing heads. Rubber eyepiece shields add comfort and block out external light interference. The 50-75mm diopter adjustment compensates for viewing abilities between each eye. The microscope base has an 80mm diameter stage with reversible and frosted stage plates that fit over the lower illuminator. Locked-on clips hold a specimen in place, and a single mid-range focus control knob moves the objective head up and down for visual adjustment. The microscope uses 110V AC and comes with a US/North American plug. The microscope also comes with a clear vinyl dust cover and instructions.

Microscopes are instruments used to enhance the resolution of an object or image. 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 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. 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 use 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.
