Abstract
A split-image, multi-power microscopic image display system and method wherein the image of an object positioned on a slide is split into two optical paths, and is magnified to a varying degree in each optical path, the resulting respective magnifications being displayed on respective monitor devices. The initial optical path includes an objective and a splitter; the path of lower magnification includes a converging lens, diverging lens, reduction lens, bending prism, TV camera and TV monitor; the path of higher magnification includes a trinocular microscope head, TV camera, and TV monitor. Further features of the invention include the following: provision of a microcomputer with data entry means, and respective mixers disposed between the TV cameras and their monitors for insertion of identifying information into the video signal and subsequent display on the monitors of the identifying information and the image of the object being microscopically viewed; provision of a photographic printer for producing a hardcopy record of the image viewed; and provision of a lens switching arrangement for selection of various objectives without the necessity of refocusing after a lens is switched into position.
