In various embodiments described herein, an optical beam shaping arrangement is disclosed. In one example, the optical beam shaping arrangement comprises a collimator for receiving light from an optical source, and providing a more collimated output, and an optical plate for receiving the more collimated output, the optical plate comprises a two dimensional array of lenses on an input side and a corresponding two dimensional array of lenses on the opposite output side. In at least one embodiment, the lenses on the input side each have a focal point at a corresponding lens on the output side, and the lenses on the output side each have a focal point at a corresponding lens on the input side, and at least some of the lenses on the output side are tilted with respect to the general plane of the optical plate.
