IR Sensing and Detection Filters
Iridian’s SWIR, MWIR and LWIR bandpass and edgepass filters are designed to optimize detection of spectral emission lines over the wavelength range of 1.6-10µm
Our thin film dielectric filters are deposited using energetic sputtering, ensuring a hard durable, environmentally stable coating. The resulting filters also have exceptionally high transmittance levels and blocking, providing the highest signal with the lowest background for your application.
- Reliability as per MIL-C-48497A
- RoHS compliant
Iridian offers off-the-shelf IR band pass filters for many of the wavelengths commonly used for gas detection.
Available gas lines include:
- H2O, CH4, CO2, CO, N2O, O3
Other wavelengths can also be supplied.
We also specialize custom-made SWIR, MWIR, and LWIR Bandpass filters for your needs. For custom requirements and quotes on our Mid IR Bandpass filters, click here.
