Abstract

In a lens system, such as for use in optical rotary joints, obliquely tilted cavities are inserted in a light path between light-waveguides and lenses to be coupled thereto in order to compensate lateral displacements between the light waveguides and the lenses. The cavities are filled with an optical medium having a predetermined refractive index in order to achieve a parallel displacement of a light-ray path, so that the ray path passes centrally through the lenses.
