Abstract

Apparatus for homogenizing light, comprising a first lens array (9) with a plurality of lenses which are arranged next to one another in a first direction (X), wherein the light to be homogenized can pass through the first lens array (9), and comprising a second lens array (10) with a plurality of lenses which are arranged next to one another in the first direction (X), wherein light which has passed through the first lens array (9) can pass through the second lens array (10) and wherein the centre-to-centre spacing (P2) of the second lens array (10) is different from the centre-to-centre spacing (P1) of the first lens array (9) such that light components which have passed through different lenses of the second lens array (10) are mutually superposed behind the second lens array (10) in the first direction (X).
