제품군의 상세 설명

  • 확산각 옵션: 0.5 - 50°
  • 고온을 견딜 수 있는 용융 실리카 기판
  • 빛이 균일하게 분포됨
  • Standard Holographic Diffuser 보유

해당 제품은 조명의 확산 영역을 제어하고 필라멘트 전구, LED, 호광등(arc lamp) 및 기타 조명의 투과율을 90% 이상으로 높이는 데 사용됩니다. 또한, 용융 실리카 기판이 사용됐기 때문에 Polycarbonate Holographic Diffuser보다 높은 작동 온도에서 사용할 수 있고, 제어가 가능하며, 빛이 균일하게 분포됩니다. 시준된 입사 빔이 확산각을 결정하며 입사각에 따라 발산각이 달라진다는 점에 유의해야 합니다.

다른 홀로그램 요소와 달리 용융 실리카를 구성하는 특정 성분의 경우 자외선(UV), 가시광선(VIS), 근적외선(NIR) 스펙트럼에 해당하는 빛을 투과합니다. 투과광의 제로 오더(반사 성분)는 가시광선(VIS) 스펙트럼에서 1% 미만이지만, 400 - 700nm 외 파장 대역에서 해당 제품을 사용하는 경우 수치가 더 높을 수 있습니다.

참고: 무광택 표면이 광원을 향해야 합니다. 홀로그램 디퓨저를 세척하려면 보풀이 없는 천에 메탄올을 적신 후 원을 그려가며 디퓨저 표면 전체를 부드럽게 닦아냅니다. 이후 곧바로 에어 스프레이를 사용하여 닦아낸 표면을 조심스럽게 불어 줍니다. 주의: 세척 시 디퓨저의 광학 성능이 변할 수 있습니다.
