제품군의 상세 설명

Calcium Fluoride (CaF2) Wedged Windows는 에탈론 효과로 인한 줄무늬 패턴을 제거하고 공진기 피드백을 방지하기 위해 30 arcmin의 웨지(wedge)를 특징으로 합니다. 이 윈도우는 낮은 흡수성에 높은 손상 임계치가 합쳐진 플루오르화 칼슘으로 제조되어 자유공간 레이저에 사용하기 적합합니다. 또한 굴절률이 낮아 무반사(AR) 코팅 처리를 하지 않고도 사용이 가능합니다. Calcium Fluoride (CaF2) Wedged Windows는 물에 잘 용해되지 않으며 기타 플루오르화 소재의 기판에 비해 높은 경도를 자랑함에 따라 환경적 요건이 거친 레이저 용도에 안성맞춤입니다. 이 밖에도 환경적 영향을 받지 않도록 하는 레이저 보호 기능이 있어 빔 샘플링 용도에 이상적으로 사용할 수 있습니다.
