제품군의 상세 설명

  • 1% 미만의 Cut-On 슬로프
  • 4.0 이상의 OD 차단
  • 투과 대역에서 91% 이상의 투과율
  • 다양한 OD 4.0 Longpass Filter Kit 이용 가능

High Performance Longpass filter는 통과대역에서 높은 투과율을, 또 차단대역에서 높은 차단을 보입니다. 차단대역에서 4.0 OD와 통과대역에서 91%이상 투과를 보이는 이러한 필터는 다양한 어플리케이션에 적합합니다. TECHSPEC® High Performance Shortpass Filters와 같이 사용할 때 미광을 줄이기 위해 특주 제작된 bandpass 필터를 사용할 수 있습니다.

Rotating Filter Wheel는 다양한 필터를 요하는 어플리케이션에 사용됩니다.
