Abstract (en)
[origin: WO2008077624A1] The invention relates to an optical rotary joint comprising a first collimator arrangement for coupling first optical fibers and a second collimator arrangement for coupling second optical fibers, wherein the second collimator arrangement is mounted in such a way that it can rotate about a rotational axis relative to the first collimator arrangement. Between the collimator arrangements, a Dove prism is provided as a derotating element. On at least one boundary surface between an optical element and the surroundings, an intermediate layer is provided which comprises a nanostructure having an average refractive index lying between the refractive index of the material of the microoptical system and the refractive index of the surrounding medium.
