レーザ光源から出るレーザ光線を修正するための装置ならびに該装置の製造方法

Japanese Patent JP2004525418

A

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 in relation to one another are subjected to a respective beam offset of a different magnitude by two different plate elements, thus compensating the distortion caused by the offset position of the emission sources. The invention also relates to a method for producing the aforementioned assembly.
