Abstract

The invention relates to an arrangement for collimating electromagnetic radiation, comprising a macrocollimator which has at least two cutouts, and microcollimator structures which are positioned in the cutouts of the macrocollimator and have lamellae that absorb electromagnetic radiation, so that collimator channels are formed which in each case extend such that they are transparent in a transmission direction.
