Arrangement for producing sharp-edged illumination line, comprises arrangement for transformation of incident radiation beam that comprises beam-splitting device and reclassification device

摘要

The arrangement comprises an arrangement for transformation of the incident radiation beam (2), which has a beam-splitting device (3) and a reclassification device (6,8). The beam-splitting device partitions the incident radiation beam in a direction (y) into two sub-beams (4a,4b,4c,4d) such that each sub-beam has a dispersion in the direction reduced in correspondence with the partitioning, and a dispersion in another direction. The redistribution device reclassifies two of the sub-beams such that the reclassified sub-beams (9a,9b,9c,9d) are arranged with the respective dispersions in the former direction abutting one another or partially overlapping.
