Abstract
According to one embodiment, 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 latter being rotatably supported relative to the first collimator arrangement about a rotation axis. A Dove prism is provided between the first and second collimator arrangements as a derotating element. The first and second collimator arrangements have at least one micro-lens array on which light-waveguides with associated ferrules are disposed. In order to avoid tensile forces from arising in the arrangement, or as a result of individual ferrules becoming interconnected by an applied adhesive, trenches, barriers, or also coatings are provided between the individual ferrules.
