Реферат: The arrangement includes two collimating cylindrical lens groups (4,8,8,8'), a focussing lens (9), and a prism block (6,6',7,7'). The prism block diverts the laser beams from adjacent emitters or emitter groups (2) into a first plane so that the collimated laser beams (S1-S3) of adjacent emitters or emitter groups are parallel to each other in mutually offset beam planes in a second coordinate direction after passing through a second cylindrical lens arrangement (8). Images of all laser beams are formed in the common spatial region or focal point (3) by the focussing lens. The deflection devices are arranged in the beam path between a first and the second cylindrical lens arrangements so that the beams are parallel before entering the second cylindrical lens arrangement.
