A nondispersive infrared sensor (or NDIR sensor) is a simple spectroscopic sensor often used as a gas is non-dispersive in the fact that no dispersive element ( 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.
