It is non-dispersive in the sense that no dispersive element is used to separate 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 correspond to the absorption region of the gas of interest. In this context, the narrow band can be 50-300 nm bandwidth. Modern NDIR sensors may use microelectromechanical systems (MEMs) or mid IR LED sources, with or without an optical filter.","extract_html":"
