Hardware module GL.scan

Hardwaremodul GL.scan

For the precise production of structures or deep engravings, the laser systems of GFH GmbH can be equipped with a scanner system that positions the laser beam on the workpiece via two mirrors. Since these optical axes only have low masses that must be moved, highly dynamic and flexible machining is possible.

GL.scan is mounted via centering elements, which allow quick and repeatable switching between different process optics. A broad range of optics is available to cover different focal diameters, scanning areas, and wavelengths.

The drift is minimized by active water cooling of the drives and regular self-calibration, thus ensuring a constantly precise machining result even over a long period of time.

The GL.scan module can be paired with a motorised beam expander to create a 3D scanning system.
