| Summary: | The invention relates to an optical observation instrument, for example a (stereo) operation microscope, having an additional shutter (
4
) in a main beam path (
2
b
), arranged between an output-reflection beam splitter (
3
) and an observer eyepiece (
5
), for respectively connecting and disconnecting the observer (
8
a
), without affecting the output-reflected signal.
As a special refinement, a special shutter design is described, which makes it possible to respectively connect and disconnect the two main beam paths (
2
a,
2
b
) and involves an override function (quick reset) for opening both beam paths. |
