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.
