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
O 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.
