Request InfoOptical Filter Source LLCAUSTIN, Texas, Jan. 31, 2013 — Optical Filter Source and Pellicori Optical Consulting have developed solar-blind UV filters for applications covering the UV regions: UVA (300 to 400 nm), UVB (280 to 300 nm) and the long-wave part of the UVC band (~225 to 280 nm). There is a need for UV bandpass filters in the UVC spectrum at wavelengths shorter than ~270 nm that possess extreme rejection of solar energy at wavelengths longer than ~300 nm. The solar spectrum contains >99% of its total energy at wavelengths longer than ~300 nm, so very high rejection is required to permit detection of UV energy. For many...See full productRelated content from Photonics MediaPRODUCTSBioPhotonics.com April 2024 IssueCOB ModuleThe M3X3L9 from Violumas, Inc. is a COB module comprised of the Violumas VC3X3 UV LED COB and a fan-cooled heatsink.
