Abstract

A microscope includes an objective lens and a pair of zoom lenses arranged in series along an optical path from the objective lens to a video camera, which converts the output of the second zoom lens to a video signal for display of a magnified first image on an associated monitor. A portion of the output from the objective lens is split to a second video camera which generates a second video signal to display a second image on the monitor, of a different magnification from the first image. The objective is fixed on a holder which can be removably mounted in a receptacle on the microscope housing and retained therein by a manually releasable latch. An optical binocular eyepiece assembly has a prism which is selectively movable into the optical path to intercept the output of the second zoom lens. Illuminating visible light is transmitted from a remote source into the optical path and through the objective lens to illuminate the object viewed. A polarizer/analyzer unit is provided. A laser source directs a laser beam via a splitter into the optical path and thence to the objective lens. The splitter is movable between a use position in the optical path and a non-use position out of the optical path.
