Ottawa, Canada, Sept 19, 2012 - Iridian Spectral Technologies Ltd. (Iridian), announces the extension of their existing visible and near-infrared (VIS-NIR) filter offerings into the mid-wave and long-wave infrared (MLWIR) wavelength region. Optical filters solutions available in this expanded wavelength range include band-pass filters (BPF), edge-pass filters (EPF), anti-reflection (AR), and beam-splitter (BS) coatings. Iridian's newly enhanced capabilities enable them to provide their high performance, reliable filters operating at wavelengths up to ~10 um for use in applications such as gas detection and milk analysis among others. This offering expands Iridian's industry leading capabilities in design and manufacture of optical filters for spectroscopy from Raman and fluorescence applications into the growing need for IR sensing.

Iridian's new MLWIR BPF capabilities provide narrow, high transmission band-pass filters in the 2-10um wavelength region enabling optical systems to detect the presence and concentration of gases of interest in environmental or process analysis applications:

Discrete detection of IR spectra for common gases:
• CH4 (3.46um or 7.73um), CO, CO2 (4.26um or 9.4um), H2O, O3
• Custom gas lines available on request

Custom sizing available:
• <3x3 mm2 for use with TO can style detectors
• 1” diameter for larger detection systems

Reliability and durability as per MIL-C-48497A:
• All dielectric hard coatings
• ROHS compliant parts

This new family of high performance MLWIR filters has been developed in response to customer needs for a reliable supplier of affordable IR detection filters. In addition to these new standards, Iridian specializes in both custom and high volume optical filter solutions.

Iridian Spectral Technologies Ltd (Iridian) – Ottawa, ON, Canada – – Iridian is a diversified optical filter manufacturer that is an international leader in filter design and manufacture especially for application in the fields of fiber optic communications, optical spectroscopy, 3D entertainment, and in aerospace.
