Abstract: Illumination arrangement for a stereo microscope, preferably a Greenough type stereo microscope, comprising at least one, preferably two illumination channels which are arranged in a plane which is arranged essentially orthogonally with respect to the plane of the two observation channels, preferably with two light channels in the interior of the microscope housing outside of the observation beam paths, wherein the light channels are guided around the observation optics.

Abstract: An exposure control system for the photographic recording of a microscope image comprises a two dimensional photographic receiver arrangement for detecting the image brightness of the microscope image. The receiver arrangement is a component part of a camera system which is attachable to a standard camera part of a microscope. The receiver arrangement has an interface for transmitting image information of a microscopic object detected by the receiver arrangement to a viewing unit. A first input device is included to which the viewing unit is coupled for manual selection of at least one optical image region on the receiver arrangement. The intensity value of the image region forming a control signal for the exposure time of the photographic recording.

Abstract: The invention is directed to a method and arrangement for generating stereoscopic images of an object. The method includes the steps of illuminating an object with an illuminating beam; masking the illuminating beam to generate a first component beam to illuminate the object at a first angle and provide a first image of the object to a first viewing eye; again masking the illuminating beam to generate a second component beam to illuminate the object at a second angle and to provide a second image of the object to a second viewing eye; and, alternately repeating the last two steps at a frequency above the flicker frequency of the human eye. In the arrangement of the invention, a beam generating device alternately generates first and second illuminating beam components which illuminate the object via illuminating optics at respectively different angles to produce respective images of the object.
