제품군의 상세 설명

  • 가시광선이나 IR 투과
  • IR-Cut 은 열을 흡수하는 필터로 적합함

IR-Cut 필터는 가시광선을 투과하고 780nm의 적외선을 차단시켜 열을 흡수하는 필터로 적합합니다. 민감한 CCD-센서 보호용으로 사용되거나 조명 시스템에 사용됩니다. 단, UV 소스의 320nm (i.e., 크세논 램프) 아래의 파장은 방사선이 세며, 투과하는 성질은 바뀔수 있습니다. UV/IR-Cut은 다층의 interference필터로서 원치 않는 UV와 IR을 막습니다. IR 보호 필터와 맞지 않는 (또는 없어진) 디지털 이미지 센서들이 있는 CCD 용도에 적합합니다. 축에서 벗어난 각도에는 영향이 적지만 각도가 큰곳에는 추천하지 않습니다. UV/VIS-Cut 필터는 UV와 가시광선을 거의 모두 흡수하고 적외선을 투과합니다. 가시광선과 적외선을 합한 적외선 이미지는 R-72 IR 필터 (720nm 이상 투과)를 추천 드립니다. 이러한 렌즈들은 보통 가시광선을 위해 디자인되었기 때문에 IR에서 깨끗한 이미지를 얻기 위해서는 초점을 맞추어야 합니다.

There is little effect on off-axis angles; however, it is not recommended for extreme angles of incidence. UV/VIS-Cut filters, also known as Infrared (IR) Pass Filters, absorb most of the ultraviolet and visible region and transmit the infrared region. For infrared images that combine visible and infrared light, we recommend the R-72 Infrared (IR) Pass Filter (which passes 720nm and above). Note that lenses are typically designed for the visible spectrum, so focusing adjustment is required to obtain clear images in the infrared.
