해당 제품은 BBAR 및 중적외선(MWIR) 어플리케이션에 맞는 고성능 경량 솔루션으로 비싼 셀렌화아연(ZnSe) 소재의 렌즈나 깨지기 쉬운 저마늄(Ge) 소재의 렌즈를 대체하기에 적합한 제품입니다. 1650 - 3000nm 파장 대역에 대한 BBAR 코팅과 3000 - 5000nm 파장 대역에 대한 MWIR 무반사(AR) 코팅이 가능합니다. 또한, 온도나 압력 변화 등 극한의 환경으로부터 받는 영향을 완화해 주는 기계적 및 열적 특성을 갖추고 있습니다. 실리콘은 밀도가 낮은 소재이기 때문에 부품이 가벼워야 하는 시스템(예: 방위 산업 관련 시스템)에도 사용할 수 있습니다.
