Mid IR Bandpass Filters

Iridian’s SWIR, MWIR and LWIR bandpass filters are designed to optimize detection of spectral emission lines.

These filters are deposited using energetic sputtering, which makes them very hard and durable.

  • Reliability as per MIL-C-48497A
  • RoHS compliant

The resulting filters also have exceptionally high transmittance levels and blocking from the visible to the LWIR. Iridian has off-the-shelf 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 provide custom-made SWIR, MWIR, and LWIR Bandpass filters for your needs. For custom requirements and quotes on our Mid IR Bandpass filters, click here.
