제품군의 상세 설명

  • NIR 파장 영역(750-1100nm)​에서 Resolution은 향상하고 Spot 사이즈는 축소하도록 설계
  • 최대 2μm의 단색 광원으로 인한 구면 수차 감소
  • 750–1550nm 영역에서 1% 미만의 반사율을 제공하는 광대역 AR 코팅

당사의 신규 TECHSPEC® Near IR doublets는 750-1100nm​ 범위의 다색광으로 인한 스폿 사이즈가 가능한 최소치가 되도록 설계되었습니다. 가시광 스펙트럼을 위해 설계된 표준 doublets를 대신해 당사의 NIR doublets를 사용함으로써, 예를 들어 다색광을 이용 시, RMS의 스폿 지름이 43μm에서 22.5μm로 줄어들 수 있습니다. 단색 광원으로 초점을 맞출 시에는 더 작은 Spot 사이즈를 갖게 됩니다. 또한, Near-IR doublets는 구면 수차를 감소시킬 뿐만 아니라 최대 2μm​ 파장의 단색 광원과 사용하게 되면 렌즈의 성능이 더욱 향상됩니다. 주요 용도로는 근적외선용 이미징 렌즈, NIR 레이저의 포커싱과 확장, 그리고 광섬유와 NIR LED의 포커싱/시준이 있습니다.
