  • Beam-forming and deflecting optical system for a laser machining device, and method for machining a workpiece using a laser beam
    Patent number: 11383323
    Abstract: A beam-forming and deflecting optical system for a laser machining device includes at least two optical elements, which are arranged one behind the other in the direction of the laser beam and which are formed by wedges with respective wedge angles, wherein at least one optical element is connected to a drive for the rotation of the optical element about the optical axis, whereby an optical wedge can be rotated relative to the at least one other optical wedge. Also a method for machining a workpiece uses a collimated laser beam. In order to achieve different shapes of the laser beam on the workpiece, each of the optical wedges, which are arranged one behind the other, in each case cover only a part of the laser beam.
