Abstract
A light coupling element is proposed with a surface (3) of a material which is transparent to light of a given wavelength (λ). In order for the light coupling element to act independently of the direction of the vectorial parameters of the light, such as in particular of the polarization, on the surface of the light coupling element line-form indentations or elevations (51, 52) are provided which are equidistantly parallel and which intersect at given angles (φ).
