ABSTRACT:
An optical rotating data transmission device comprises a first collimator arrangement for coupling-on first light-waveguides, and a second collimator arrangement for coupling-on second light-waveguides, which is supported to be rotatable relative to the first collimator arrangement about a rotation axis. A Dove prism is provided between the collimator arrangements as a derotating element. Furthermore, the collimator arrangements pre provided with adapter elements having rotationally symmetrical conical faces. Prism adapter elements are disposed on the end faces of the Dove prism and have prism adapter elements on the sides facing the collimator arrangements. These also have rotationally symmetrical conical faces with a surface configuration that is inverse to that of the adapter elements of the collimator arrangements.
