OTTAWA, 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 environmental or process analysis applications, including discrete detection of IR spectra for CH4, CO, CO2, H2O and O3.
Custom gas lines are available upon request, and custom sizing is available (<3 × 3 mm2 for use with TO can-style detectors; 1-in. diameter for larger detection systems).
The filters meet the MIL-C-48497A standard and include all dielectric hard coatings and RoHS-compliant parts.
