Device for the optical beam transformation of a linear arrangement of several light sources

摘要

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 ( 4 A) that are arranged adjacent to one another in fixed allocation, wherein the distance between two adjacent single lenses ( 4 A) is smaller than the distance between two adjacent linear optical emitters ( 2 ).
