제품군의 상세 설명

  • 0° 입사각용으로 설계
  • 400 - 700nm에서 표면당 1.75% 미만의 반사율 제공
  • VIS 0°VIS-NIR Coated Achromats 또한 이용 가능

Achromatic doublet lens는 두 개의 광학 부품이 접합된 아크로매틱 이중렌즈로서 광축 상의 구면 수차와 색 수차를 보정하기 위해 컴퓨터로 최적화 처리 과정을 거칩니다. 당사의 achromatic doublet은 가시광 영역을 위해 단층 MgF2 코팅이나 광대역 다층 코팅을 적용할 수 있습니다. 이외에도 NIR achromatic doublet 및 edge blackened achromatic doublet 또한 구매가 가능합니다.

Achromatic doublet lens는 다색("백색광") 이미징에서 단순 렌즈보다 훨씬 더 뛰어난 성능을 갖습니다. 2개의 광학 요소가 짝을 이루어 하나의 achromatic doublet lens(말 그대로 "무색 렌즈")를 생성함에 따라 글래스에 내재된 색 분리(color separation)를 보정할 수 있습니다. 색 수차와 구면 수차가 제거된 achromatic lens는 다색 조명과 이미징 용도에서 최고의 가성비를 제공합니다.
