Iridian Spectral Technologies

Iridian designs and manufactures custom optical thin film filter solutions from the UV (300nm) into the LWIR (10um). Our wavelength selective dielectric thin-film filters provide "More Signal and Less Background" to our customers' systems with long term durability and reliability combined with industry leading optical performance at affordable prices. We customize optical filter solutions for use in spectroscopic applications, tele/datacom systems, 3D entertainment, space and satellite, LiDAR, and many more customer applications. 

Founded in 1998 and located in Ottawa, Canada, Iridian Spectral Technologies is a world leader in optical filters for a wdie range of applications.  Iridian's highly advanced, proprietary thin-film technology delivers durable, high performance filters for use in telecommunications products, spectroscopic instrumentation and lasers, as well as being applied to other applications in biophotonics, environmental and process gas sensing, aerospace (earth observation and sat-com), 3D entertainment and many more. Iridian works closely with its customers from the early stage of their product's development in order to ensure that the best balance between technical and commercial needs is provided, supporting the customer product journey from initial prototyping to volume manufacturing. The company has developed a high degree of automation in order to ensure supply of high quality and low cost products and is ISO9001:2015 certified. It has an unparalleled capability to produce both high volume commodity filters and high precision custom thin film filters. 

Iridian provides many different filters types spanning the wavelnegth range of ~300nm to 10um including:

  • CWDM and DWDM X skip 0, gain-flattening (GFFs), dual-band filters, and coated Si etalons for tele/datacom
  • band-pass, edge-pass, notch filters and multi-band or multi-notch filters for spectroscopy and biophotonics
  • large highly uniform narrow band filters for astronomy
  • multi-zone filter arrays for multispectral imaging in process monitoring or earth observation
  • multi-notch 3d cinema glasses
  • narrow band, low angle shift bandpass filters for LiDAR
  • MWIR bandpass filters for gas sensing and detection
