Patent ID: 8469549

Claim:
Beam shaper for a light source arrangement for generating a radiation profile, comprising: a multitude of adjacently arranged optical beam-shaping elements, wherein the beam-shaping elements each belong to one type of a plurality of different types of beam-shaping elements with different optical characteristics, the different types of beam-shaping elements generate respective light distributions in a far field or in a finite image target when illuminated; wherein the beam-shaping elements, when illuminated together, generate the radiation profile of the beam shaper by a superposition of the respective light distributions of the different types of beam-shaping elements; and wherein the beam-shaping elements each comprise an intensity-modulating element and a refractive element associated with the intensity-modulating element, the refractive element arranged downstream of the intensity-modulating element with respect to an optical path of the beam-shaping elements.
