This microscope was used for demonstration purposes and is still in good, fully-functional condition. All the quality features and versatility of larger stereo models, in a compact size—only 12” tall. Ideal size for elementary and middle school, yet rugged enough for high school.

Head rotates 360 degrees to permit reverse head position viewing. High intensity 12v, 10 watt incidental and transmitted illumination is built in. Base mounted switches control on/off, separate top or bottom light, or both lights together. Rack and pinion focusing.
