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 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.

They are used to isolate certain wavelengths or colors. Applications range from detecting the gaseous composition of a distant star to visualizing the chemical activity in a human cell. Ultraviolet (UV) bandpass filters (with effective wavelength ranges below 400 nm) pose unique design and manufacturing challenges related to the absorption of materials at short wavelengths.In their earliest forms, UV bandpass filters that were optimized for wavelengths less than 400 nm, such as the Schott UG or the Hoya U-series, were constructed of absorbing compounds in glass. Such...Photonics HandbookThin-Film Coatings: A Buyers' Guide: The vast majority of optics used in precision scientific, industrial, biomedical, and military applications incorporate thin-film coatings on their surfaces. Therefore, it’s useful for almost anyone involved in the specification and purchase of optical components to have some familiarity with the typical performance characteristics, trade-offs and limitations of various coating types, as well as some knowledge of the capabilities of common thin-film production technologies. This article provides an objective overview of both these topics.What are thin-film coatings? The purpose of any optical thin-film coating is to modify the transmittance and reflectance properties of the substrate material to which they are applied.
