제품군의 상세 설명

비코팅 옵션 제공 혹은 자외선(UV), 가시광선(VIS) 및 근적외선(NIR) 스펙트럼으로 BBAR 코팅 처리 가능
이미징 어플리케이션에 적합
5 - 200mm의 표준 직경 크기
1λ 및 λ/10 UV Fused Silica Window 보유

해당 제품의 제조 사양은 표면 품질이 40-20, 투과 파면 오차가 λ/4이며, 이미징 어플리케이션에서 사용하기에 적합합니다. UV 용융 실리카 기판이 특징인 제품으로 자외선(UV)부터 근적외선(NIR)에 이르는 파장 대역에서 투과율이 높습니다. BBAR 코팅 옵션을 선택하면 반사 손실을 최소화하고 투과율을 높일 수 있습니다. 해당 제품은 광학 이미징 및 중출력/저출력 레이저 어플리케이션에 사용되거나 자외선(UV) 광원을 투과시켜야 하는 보호용 윈도우로 사용할 수 있습니다.
