Abstract

The invention relates to an assembly for correcting laser illumination emitted from a laser light source, comprising a laser light source, which has linear emission sources that are arranged in a row in a first direction (X), whereby in addition, the emission sources that are arranged essentially in a row are at least partially offset relative to the row in a perpendicular direction (Y) in relation to the first direction (X). The assembly also comprises corrective elements, which can correct the laser illumination emitted from the laser light source in such a way that the spatial distortion of the laser illumination, caused by the offset position of the emission sources relative to the row, is compensated. According to the invention, the corrective elements are configured as a plate array that comprises a number of plate elements consisting of substantially plane-parallel plates that are transparent to the laser illumination used. At least two of the plate elements have a different thickness and the corrective mans is located in the laser illumination emitted from the laser light source, in such a way that the light beams emitted from at least two emission sources that are offset i…
