摘要

The revolver (1) has a carrier (3) provided with accommodation devices (7) for an optical element (E) and a frame (2) and rotatably supported relative to the frame around a spatial rotation axis (X). The accommodation devices are circularly exchanged against each other, so that axial positioning of the carrier takes place at three projections (9) in an accurate manner. The projections are arranged at distance from the rotation axis. The accommodation devices comprise three contact points for the optical element. The carrier is radially supported on an axis (4) formed along circumference.
