Abstract: A depolarizing homogenizer comprises one or more lens let arrays, for providing a plurality of beamlets associated with different respective parts of a received beam. The depolarizing homogenizer comprises a depolarizer comprising different areas which affect polarization differently, the depolarizer being positioned to cause alteration of the polarization characteristics of at least some of said plurality of beamlets. A lens is arranged to at least partially overlap the said beamlets having said altered polarization characteristics.
