ABSTRACT:
A TV-photography system for a surgical microscope, said system being constructed in such a manner that an optical path, which extends from an objective lens to an eyepiece, is divided by a beam splitter and an imaging adapter equipped with a shiftable built-in mirror is positioned on a divided-out optical path so as to operably guide the divided-out optical path to either a television camera or a still photographic camera, which system comprises control means adapted to operate the shiftable built-in mirror and still photographic camera successively in accordance with a preset sequence so that, in the course of displaying a selected region on a monitor TV by means of the television camera, a still picture of the selected region can be automatically taken by inputting only a prescribed start signal to the control means. The above system enables to automatically take a series of still pictures without need for interrupting the operation. There is no danger to contaminate a sterilized drape which normally covers the surgical microscope. Resulting still pictures are absolutely free from camera-shake and are thus very sharp.
