24 Sep 2012 Iridian Spectral Technologies Ltd. (Iridian), announces the extension of our 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. Our newly enhanced capabilities enable us to provide our 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. Please contact us to discuss any optical filter needs.
