Abstract
A device for combining light beams which interact with adjacently arranged pixels of a light modulator, having a beam splitting component, a beam combining component, and a beam superposition component. The beam splitting component is configured such that incident light beams are split into a first subbeam and a second subbeam so that the first subbeam propagates toward a first pixel of the light modulator and the second subbeam propagates toward a second pixel of the light modulator. The beam combining component is configured and arranged so that the first subbeam and the second subbeam are combined after interaction with pixels of the light modulator. The beam splitting component and the beam combining component are configured and arranged in such a way that a sum of optical path lengths of the first subbeam and the second subbeam is respectively constant for different angles of incidence.
