Abstract
A viewing tube for an optical device and in particular for a microscope is described, in which there are provided in the beam path of the viewing tube beam splitters that deflect a portion of the light out to a simultaneous observation tube and/or to an imaging or recording unit, or reflect light from a display and/or processing unit into the beam path. In each beam path of the viewing tube there is provided only one beam splitter, which is rotatable about the optical axis of the respective beam path and always remains in the working position in the beam path. The respective beam splitter, depending upon its rotational position, deflects the reflected-out portion of the light into the corresponding beam path of the simultaneous observation tube or of the imaging or recording unit, or couples light into the beam path of the viewing tube.
