Abstract

An apparatus for homogenizing light, including a lens array (5, 7, 8) with a plurality of lenses (6, 9, 10) through which the light to be homogenized can pass. The apparatus has at least two different center-to-center distances of the lenses (6, 9, 10) of the lens array (5, 7, 8), wherein the center-to-center distances of the lenses (6, 9, 10) decrease or increase from the inside to the outside.
