Request InfoIridian Spectral TechnologiesOTTAWA, Ontario, Canada, Sept 24, 2012 — Iridian Spectral Technologies Ltd. has extended its visible and near-infrared filter offerings into the mid- and long-wave infrared wavelength regions. Optical filters in the expanded wavelength range include bandpass and edge-pass filters, and antireflection and beamsplitter coatings. The filters operate at wavelengths up to ~10 μm for use in applications such as gas detection and milk analysis. The narrow, high-transmission bandpass filters in the 2- to 10-μm wavelength region enable optical systems to detect the presence and concentration of gases of interest in...See full productRelated content from Photonics MediaPRODUCTSPromoted Content August 2023 IssueMulti-Bandpass Optical FiltersThe commercial availability of Light-Emitting Diodes at almost any wavelength combined with Multi-Bandpass Filters have enabled a completely new type of instrumentation.
