Request InfoIDEX Health & Science - Semrock Optical FiltersNear-IR hard-coated bandpass filters have been announced by Semrock. Keyed to popular laser lines in the 1500- to 1600-nm spectral region, they are suitable for use as laser source cleanup filters and as detection filters that pass particular laser wavelengths and that virtually eliminate background noise over the full InGaAs detector range from 850 to 1750 nm. They are optimized for retina-safe lasers in the 1.5-μm range. The filters match well with erbium-doped fiber and glass lasers at 1535 nm, erbium-doped fiber and InGaAsP semiconductor lasers at 1550 nm and Nd:YAG-pumped optical...See full productRelated content from Photonics MediaPRODUCTSPromoted Content February 2023 IssueCustom WL Selective Optical FiltersIridian Spectral Technologies designs and manufactures wavelength selective optical filter solutions providing “more signal, less background”, customized to meet the technical and...Promoted Content October 2022 IssueIR FiltersDSI designs and manufactures thin film coatings such as bandpasses, beamsplitters, ARs, and absorption coatings for use in the MWIR thru LWIR wavelength regions.
