Abstract
The invention relates to an optical collimator for focusing light by means of a plurality of optical surfaces, which are designed as light entry surfaces and/or light exit surfaces and/or reflection surfaces, which form respective optical boundary surfaces with a change in the optical density. The aim of the invention is to propose a collimator by means of which homogeneous illumination is possible even if a plurality of light sources is used, the collimator having a compact design and being economical to produce. This aim is achieved, according to the invention, in that the collimator has a plurality of concave micro-lenses (), which are formed on at least one of the optical surfaces.
