Patent ID: 8314361

Claim:
A device for laser machining, the device comprising: an optical system including a collimator, one or more deflecting optics, and a machining head, the optical system configured to provide an optical beam path for laser light from an input of the collimator to an output of the machining head, the collimator comprising one or more collimating optics arranged in the optical beam path and configured to direct the laser light along a collimator axis, the machining head including one or more focusing optics and configured to direct the laser light through the output towards a workpiece, the one or more deflecting optics arranged between the collimating optics and the focusing optics and configured to deflect the laser light emerging from the collimating optics towards the focusing optics, wherein the machining head is adjustable relative to the workpiece with dynamic adjustment movements along a z-direction perpendicular to the workpiece and wherein the collimator projects in the direction of an axis of the collimator and the collimator axis extends transversely to the z-direction while the collimator is fixed in the z-direction.
