Zusammenfassung:	The device has homogenizers (5, 6) with an input surface (7) and output surface (8) for a laser beam that is to be homogenized. Two sets of array of cylinder lenses (9) are arranged on the input surface and the output surface of the homogenizers, respectively. Cylindrical axes of the lenses are oriented in a parallel manner with respect to each other. Focal planes of the lenses are arranged on both the output and input surfaces. Independent claims are also included for the following: (A) an arrangement for illuminating a surface (B) an arrangement for focusing the light from a laser light source into a linear focusing area.
