Definitions

  • the invention provides for determining the position of the laser focus or the adjustment of the position of the laser focus relative to the at least one workpiece with a pilot laser beam whose intensity is preferably less than that of the actual processing laser beam.
  • the pilot laser beam should be parameterized so that, while it can be reflected off the workpiece and imaged on the sensor unit, it does not melt the workpiece. It is essential that the focus position of the pilot laser beam corresponds to the focal position of the processing laser beam, the pilot laser beam therefore preferably covers at least partially the same optical path as the actual processing laser beam.
  • a digital camera for example CCD, CMOs, etc.
  • the photodiodes of the digital camera can be designed to operate in the IR radiation range or in the visible radiation range.
  • the evaluation of the image with a suitable image processing software based on a brightness distribution of the image and / or based on the sharpness of the image or the radial extent of the laser beam ring.
