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.
