Device for homogenizing light and configuration for illuminating or focusing with such a device

摘要

A device for homogenizing light contains at least one homogenizer device having an entrance surface and an exit surface for the light that is to be homogenized. An array of cylinder lenses is disposed on the input surface and an array of cylinder lenses is disposed on the output surface of the at least one homogenizer. Cylinder axes of the cylinder lenses of the at least one homogenizer are oriented in a parallel manner in relation to each other. A configuration for illuminating a surface and to a configuration for focussing the light from a laser light source into a linear focussing area use the device for homogenizing.
