  • Nondispersive infrared sensor - Wikipedia

    A nondispersive infrared sensor (or NDIR sensor) is a simple spectroscopic sensor often used as a gas detector.It is non-dispersive in the fact that no dispersive element (e.g a prism or diffraction grating as is often present in other spectrometers) is used to separate out (like a monochromator) the broadband light into a narrow spectrum suitable for gas sensing.

  • NDIR Sensor for Non-Dispersive Infrared Detection

    IR Gas SensorsNon-Dispersive Infrared (NDIR) SensorsEliminating ErrorsAre You Looking For An Ndir Sensor?Commercial IR gas sensors generally consist of an infrared source, a detector, a gas cell/path, a wavelength selection device and some optical components (lenses or more usually mirrors) to couple the radiation from the source through the gas cell to the detector. The sample gas passes through the gas cell and the detector measures the radiation at the absorption band wavelength of the target gas. When no target gas is present there is no absorbance so the signal reaching the detector is at a maximum. When the target gas is present in the path, the detected signal reduces as the target gas concentration increases.
