회절 광학 소자(DOE)

Coherent 사용하여 가우시안 레이저 빔을 다른 강도 분포로 변환함으로써 다양한 재료 가공 응용 분야에서 최적의 결과를 얻을 수 있습니다.

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.
