Abstract
Abstract A transparent multifunction display field (LCD display 23) is reflected by means of a transmitted-light projection ray path (21-27) into the intermediate image plane (11) of a photomicroscope. The LCD display (23) provides the viewer with information on the status of the microphotographic system by showing, superposed on the object image, corresponding symbols and numbers, illustratively for the nature and picture format of the camera used, its exposure counter, position and size of the spot used for the exposure-time measurement, the thus-determined exposure time, flashlight function, etc.
