Abstract: An optical arrangement for collimation of a plurality of laser beams of several emitters or emitter groups of a laser diode arrangement which are located in one row or in several rows, the emitters or emitter groups of one row being located with their active layer in one common plane with a stipulated distance A in one axial direction, the arrangement including two sets of cylindrically acting collimation optics, wherein the arrangement includes means for deflection of the laser beams after passage through the two sets of collimation optics which are present parallel to one another in different beam planes offset against one another.
