Our narrow band filters offer a high signal-to-noise ratio that enables identification of any gas with a signature in the IR spectrum.   Filters with a center wavelength of 3330 nm are commonly used to detect, quantify and image methane. 


A unique feature of our product is that multiple filters can be patterned or bonded into an array which allows the customer to use a single detector to detect multiple gases.  Our narrow band filters for gas sensing are available in a broad range of bandwidths, or custom-made based on your requirements.

  • High volume low cost
  • High reliability and repeatability
  • Low band shift with temperature
  • Low band shift with angle
  • NO band shift with temperature
