An optical instrument has an outer shank () with a viewing window () arranged near the free shank end and a handle part () at the other end of the outer shank. An opto-electrical a transducer () is rotatably arranged within the outer shank, and is attached on an inner shank () which is rotatably mounted within the outer shank. Actuation means () for rotating the transducer () are provided in the outer shank. An axial bearing is provided between the outer shank and the inner shank (). Moreover, a spring element impinging the inner shank () with force in the direction of the axial bearing is provided.

Optical instrument

An endoscope, in particular a mediastinoscope, in which the handle and the optics guided therein form an inseparable unit and which includes a first and second spatula-like part which can be separated from one another in the longitudinal direction. An adjusting mechanism is provided which permits a separation, a fastenable displacement parallel to the axis and a fastenable pivoting of the two parts relative to one another. In particular by way of the pivotability an expansion of a body cavity to be visually examined or which is to undergo therapy by way of introduced auxiliary instruments is made possible according to requirements.
