Abstract:
Optical assembly for symmetrizing the radiation of a plurality of laser diodes arranged adjacent to each other in the y-direction in fixed coordination, which radiate in the z-direction and whose radiation in the x-z and y-z planes is asymmetrical, a cylindrical lens system being mounted behind the laser diodes, wherein the cylindrical lens system is arranged tilted about the optical axis (z-axis) which is perpendicular to the x-y plane and collimates the output beams of the individual laser diodes in the x-direction and shifts them relative to each other and separates them in the process, in that behind the cylindrical lens system is mounted a first deflection element which deflects the beams of the individual laser diodes in the y-direction with different angles of deflection such that at a predetermined distance the centroids of the individual beams coincide, and in that a distance behind the first deflection element is arranged a second deflection element which recompensates the different angles of deflection of the beams relative to the optical axis (z-axis).
