A device for homogenizing light contains at least one optically functional surface through which light to be homogenized can pass and a plurality of concave and convex cylindrical lenses which are disposed in an alternating fashion one next to the other on the at least one optically functional surface. The device further has at least one first embodiment and at least one second embodiment, different from the at least one first embodiment, of transitions between the concave and the convex cylindrical lenses. Wherein the transitions between the concave and the convex cylindrical lenses are configured such that partial beams of the light to be homogenized, which have passed through different embodiments of the transitions between the concave and the convex cylindrical lenses, have an optical path difference with respect to one another, which contributes to the reduction of interference effects in the homogenized light.
