Abstract

An optical device forms a beam path between an optical end element at a beam path end and an object scene into which the beam path is directed via a field of view of the end element. The optical device contains an alignment device for pivoting the field of view relative to a predetermined direction, an end optical unit and an optical articulation for guiding the beam path from the pivoted field of view into the end optical unit. In order to achieve good shielding against spurious radiation, the device has a shielding unit containing a shielding element led partly around the optical articulation, which shielding unit shields the optical articulation against incident radiation that is not incident through the entrance or exit aperture of the optical articulation.
