Device and method for homogenizing optical beams

摘要

A device for homogenizing optical beams contains at least one optically functional boundary surface through which a beam to be homogenized can pass or at which a beam to be homogenized can be reflected. A plurality of lens elements or mirror elements are disposed on the at least one optically functional boundary surface. The lens elements or the mirror elements each have such a curvature in their edge regions that diffraction-related effects are reduced as a result.
