An optical device for homogenizing a light beam comprises a plurality of first lenses on which the light beam impinges from one side. At the side on which the light beam impinges the first lenses are convex, while they are prismatic at the opposite side at which the light beam emerges from the lenses. At least one convergent lens is disposed downstream of the lenses mentioned in the direction of the light beam. Instead of giving the first lenses a prismatic configuration it is also possible to make the first lenses plano-convex and arrange second lenses of plano-concave shape downstream of the first lenses in the direction of the light beam.
