Abstract:
1. An arrangement for optical beam transformation, comprising: at least one light source which can emit at least one light beam, with the at least one light beam having a greater divergence in a first direction (Y) than in a second direction (X) at right angles to it; a collimation means, which can at least reduce the divergence of the at least one light beam in the first direction (Y); an apparatus for optical beam transformation, which is arranged downstream from the collimation means in the propagation direction (Z) of the at least one light beam, with the apparatus such that the divergence of the at least one light beam passing through the apparatus in the first direction (Y) is interchanged with the divergence in the second direction (X) at right angles to it; wherein the apparatus for optical beam transformation is such that the cross-sectional area of the at least one light beam is reduced in the apparatus for optical beam transformation.
