Gas Sensing

Optical filters with dielectric coatings play a pivotal role in Non-Dispersive Infrared (NDIR) gas sensing. These innovative filters enable precise detection of various gases by selectively allowing specific wavelengths of infrared light to pass through, enhancing the accuracy and sensitivity of gas sensors. Our customizable dielectric coatings offer unparalleled control over filter characteristics, ensuring accurate gas concentration measurements across a wide range of applications, from environmental monitoring and industrial safety to thermal imaging and fire detection.

This versatility supports the detection of multiple gas lines within the same sensing device, covering wavelengths from the short wave-infrared to the far-infrared regions of the spectrum. The ability to coat large areas with superior control on wavelength tolerance and band shape characteristics makes us the choice in the industry.
