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 respectively magnified images being displayed on respective monitor devices. The initial optical path includes an objective and a splitter; the paths of lower magnification and higher magnification each include a TV camera and a TV monitor, and may include various optical elements in accordance with the four disclosed embodiments. 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, with 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.
