Abstract

The present invention pertains to an optical symmetrization device for symmetrizing the radiation emitted by laser diodes. The symmetrization device contains a cylindrical lens system (3), a cylindrical lens array (4) and a deflection element (5). The cylindrical lens array (4) contains at least two cylindrical single lenses (4A) that are arranged adjacent to one another in fixed allocation, wherein the distance between two adjacent single lenses (4A) is smaller than the distance between two adjacent linear optical emitters (2).
