Nondispersive infrared sensor Wikipedia

A nondispersive infrared sensor is a simple spectroscopic sensor often used as a gas detector. It is nondispersive in the fact that no dispersive element is used to separate out the broadband light into a narrow spectrum suitable for gas sensing. The majority of NDIR sensors use a broadband lamp source and an optical filter to select a narrow band spectral region that overlaps with the absorption region of the gas of interest. In this context narrow may be 50300nm bandwidth. Modern NDIR …
