Abstract

An arrangement in which a reflection lens system shapes and guides beams from a rectilinear laser diode array with beam outlet surfaces lying in a common plane is disclosed In order to map the beams from the individual laser diodes to form a substantially uniform radiation field or pattern using such an arrangement, at least one first reflection component having a reflection surface is associated with each beam in order to bring together the individual outlet beams. The reflection surfaces are disposed in mutually offset planes, the offset corresponding sequentially to the sequence of the laser diodes in the array.
