一般光学

回折光学素子(DOE)

Coherent (光学設計素子)を使用することで、ガウスレーザービームを他の強度分布に変換し、さまざまな材料加工用途において最適な結果を実現します。

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.
