제품군의 상세 설명

2 - 200mm 크기의 원형/정사각형 제품
7가지 BBAR 코팅 옵션 제공
표준 N-BK7 윈도우 최다 보유
Ultra-Thin N-BK7 Window 보유

해당 제품은 산업 및 저출력 레이저 어플리케이션에 적합합니다. 공차가 높도록 설계되어 빔 왜곡과 산란을 최소화합니다. 광대역 코팅 옵션 선택 시 이러한 정밀 윈도우의 파장 대역이 가시광선(VIS)부터 근적외선(NIR)에 이르는 스펙트럼으로 확장됩니다. 또한, 2 - 200mm 크기의 원형/정사각형 제품으로 제공됩니다.

참고: 해당 제품군에 새로 추가된 제품은 사양에 표면 평탄도 대신 투과 파면 왜곡(TWD)이 명시될 수 있습니다. 두 사양의 차이점에 관한 자세한 내용은 어플리케이션 노트 중 'Understanding Optical Windows(광학 윈도우 이해하기)'를 확인하세요.
