근적외선용 F-Theta 스캔 렌즈

황화아연 다중 스펙트럼 및 용융 실리카 소재를 기반으로 한 스캔 렌즈를 사용하여 레이저 용접, 마킹, 조각 및 절단 분야의 성능을 최적화하십시오.

Zinc sulfide multispectral has high thermal conductivity for reduced thermal focus shift and a high refractive index to minimize component count. Especially when combined with aspheric surfaces, this delivers better performance and lighter weight.
