Abstract:
1. An arrangement for correction of laser radiation emanating from a laser light source, comprising the laser light source which has linear emission sources which are located essentially in at least one row in a first direction (X), the emission sources located essentially in a row being offset in the direction (Y) perpendicular to the first direction (X) at least partially to the row, and the arrangement further comprising correction means which can correct the laser radiation emanating from the laser light source such that the three-dimensional distortion of the laser radiation caused by the offsetting of the emission sources to the row is equalized, wherein the correction means are made as a prism array, the prism array comprises individual prism elements, the laser radiation passing through the prism array, at least two of the prism elements having different prism angles, the individual prism elements arranged in the laser radiation emanating from the laser light source such that the light beams emanating from at least two emission sources which are offset to one another are incident on different prism elements and are deflected on one of their prism surfaces at a different angle such that the distortion caused by the offset of these emission sources is corrected.
