Abstract (en)
[origin: WO2005103795A1] The invention relates to a device for optical beam homogenization, which comprises at least one optically functional boundary surface for passage of a beam to be homogenized or for reflection of a beam to be homogenized, and a plurality of lens elements (4, 5) or mirror elements that are disposed on the at least one optically functional boundary surface. The lens elements (4, 5) or the mirror elements are curved in their marginal areas to such an extent as to reduce diffraction-related effects.
