Abstract (en)

[origin: WO0127686A1] The invention relates to a device for symmetrizing radiation emitted from one or more of several linear optical emitters, in particular wide strip laser diodes. The device has, per emitter (1, 1a, 1b) a cylindrical lens optical system (2, 2a, 2b) each comprising one or more cylindrical lenses which collimates each beam in a direction y whereby each beam is deflected in a direction y at a different angle as a result of a rotation about the axis z of at least one of the cylinder lenses or by providing a discontinuous deflection element. The device also contains a director-collimator optical system (3), which collimates each radiation beam in the direction x and deflects said beams at different deflection angles in such a manner that the main beams of the individual radiation beams coincide in the direction x at a defined distance from the emitter and run in parallel in the direction y. The device has a redirector optical system (4), which compensates for the deflection of the radiation beam caused by the director-collimator optical system (3) in the direction x.
