DEVICE AND METHOD FOR MODIFYING THE SURFACE OF A WORKPIECE USING PHOTONIC RADIATION

摘要

The invention relates to a device and a method for modifying the surface (1') of a workpiece using photonic radiation (2), especially laser radiation. Said device comprises a radiation source (3) and a mask device, said mask device being configured by a support (7), permeable to the radiation (2), to whose side facing the workpiece (1) individual lens elements (9) are adhered and the radiation (2) is bundled into partial beams (10) by the individual lens elements (9).
