Abstract:
1. An optical symmetrization device for symmetrizing the radiation emitted by a plurality of linear optical emitters that are arranged adjacent to one another in fixed allocation in a first x-direction, wherein said emitters emit in a common z-direction that extends perpendicular to the x-direction, and wherein the output beam clusters of said emitters have a significantly lower beam quality in the x-direction than in the y-direction that extends perpendicular to the x-direction and to the z-direction, comprising: a cylindrical lens system arranged downstream of the optical emitters in the z-direction and that comprises one or more cylindrical lenses that collimate and transform the output beam clusters of the individual emitters in the y-z plane, wherein at least one of the cylindrical lenses of the cylindrical lens system is arranged such that it is tilted about the z-axis and/or an optional deflection element is arranged downstream of the cylindrical lens system in the z-direction, such that the output beam clusters of the individual linear optical emitters are respectively deflected in the y-direction by a different angle, a first deflection element that is arranged downstream of the cylindrical lens system in the z-direction and respectively deflects the beam clusters of the individual linear optical emitters in the x-direction by a different angle, such tat the principal beams or centroidal beams of the individual beam clusters coincide at a predetermined distance, and a second deflection element that is arranged downstream of the first deflection element in the y-direction and spaced apart therefrom by a predetermined distance, wherein the second deflection element deflects the beam clusters of the emitters in such a way that the deflection of the beam clusters caused by the first deflection element is compensated in the x-z plane, wherein the first deflection element comprises at least one cylindrical lens array with at least two cylindrical single lenses that are arranged adjacent to one another in the x-direction, wherein two adjacent single lenses are spaced apart by a distance that is smaller than the distance between two adjacent linear optical emitters.
