Beam Shaper

Photonics Spectra

MolTech GmbH is offering improved versions of its Focal-πShaper beam shaping systems. The instruments convert a Gaussian laser beam into a beam whose shape is optimized to create a flattop, donut, reverse Gauss or other intensity profile near the focal plane of a focusing lens installed after the shaper. This increases energy efficiency, reduces the heat-affected zone and produces steep edges and accurate profiles of kerfs. The beam shapers can work with scanning heads and f-Theta lenses, and models are available for the near-IR, visual and infrared regions, as well as for CO2 lasers. Applications include laser marking, scribing, dicing, micromachining, photovoltaics, drilling and controlled laser heating.
