Patent ID: 8415584

Claim:
A modular laser processing system for processing a workpiece by means of a processing laser beam, which system has a multiplicity of functional modules with a beam passage region which can be connected to one another in series along a processing laser beam path, comprising: a functional module embodied as a fibre connection module and serving for accommodating a fibre end from which the processing laser beam emerges, and a functional module embodied as a collimator module and having a collimator lens, which collimates the processing laser beam, wherein the collimator lens is selected from a group of collimator lenses having different focal lengths which correspond to a raster dimension or to an integer multiple thereof, wherein a length of the beam passage region of a functional module along the processing laser beam path corresponds to the raster dimension or to an integer multiple thereof, wherein the multiplicity of functional modules comprises a z adjustment module, which has a mount adjustable in the z direction and suitable for accommodating a fibre bush, a collimator lens or a focusing lens, and/or wherein the multiplicity of functional modules comprises an x or y adjustment module, by means of which functional modules arranged beam-upstream with respect to the adjustment module can be adjusted in an x or y direction relative to functional modules arranged beam-downstream with respect to the adjustment module.
