Apparatus for shaping a light beam
First Claim
1. An apparatus for shaping a light beam, comprisingat least two optically functional boundary surfaces that are arranged one behind another in the propagation direction (z) of the light beam to be shaped, such that the light beam can pass through the at least two optically functional boundary surfaces one after another;
- andtwo groups of refractive or diffractive imaging elements that are arranged on at least one of the optically functional boundary surfaces;
whereinat least two of the imaging elements have different properties within at least one of the groups andwhereinthe diffractive imaging elements are grating-like structures or periodic variations in diffractive index.
