Abstract
A method for processing workpieces by means of high-energy radiation, wherein the radiation is focused by a processing optic onto a processing site. The light radiation emanating form the workpiece is received by the same processing optic and is analyzed by a detector. An optical measurement with respect to the surface of the workpiece is performed in a processing area of the workpiece by means of an external source of measuring light, utilizing measuring light reflected from the processing area. The same processing optic is used to focus radiation onto the processing site and to receive radiation emanating from the workpiece at the processing site.
