Allgemeine Optik

Diffraktive optische Elemente (DOE)

Wandeln Sie mit Coherent gaußförmige Laserstrahlen in andere Intensitätsverteilungen um, um bei einer Vielzahl von Materialbearbeitungsanwendungen optimale Ergebnisse zu erzielen.

Coherent DOEs are built for use in demanding industrial applications – high-power laser welding, PCB drilling, glass cutting, solar cell manufacturing, and more – and are characterized by high efficiency, low stray light, and high damage threshold.

DOE Fabrication Capabilities

Specify DOEs with various functional capabilities, including a top hat, rectangular, or ring beam shaper, and 1D/2D beam splitter or arbitrary ratio beam splitter.
