The shorter wavelength offers tighter focusing and increased absorption that enables high precision structuring. The prototype UV micro scanner achieves excellent quality and repeatability for surface structuring with feature sizes down to 400 nm.

First test of the new optical module with 8 flexible multibeams, boosting process performance more than a factor of 4 already! In the next months, 7 identical optical modules will follow to complete the 64 flexible multibeam tool. The demonstrator machine is equipped with a 1 kW ultra short pulsed laser and designed to significantly increase productivity of laser microstructuring.

In the project “FOCUS” we develop a sensor-based position detection and control system to combine the best of two worlds: The flexibility of a commercial, cost-effective 6-axis robot and the precision of ultrashort pulsed microstructuring.

One of the key technologies to increase productivity of laser micromachining and maintain the high level of surface quality is multibeam processing. The multibeam technology has already found its way into industrial production for consumer electronics or medical products. Here, the generation of flexible surface structures for embossing tools or micro-drillings for filter applications with feature sizes down to 1 µm have been demonstrated.
