ABSTRACT:
An optical rotary joint comprises a first collimator arrangement for coupling-on first light-waveguides, and a second collimator arrangement for coupling-on second light waveguides, with the second collimator arrangement being supported to be rotatable relative to the first collimator arrangement about a rotation axis. At least one derotating optical element is provided in the light path between the first collimator arrangement and the second collimator arrangement. At least one collimator arrangement comprises a rod-shaped lens that is fastened on a support plate so that the axis of the lens is tilted at a given angle relative to the rotation axis of the rotary joint.
