Whether used for breath gas or the surrounding air, gas measurements using NDIR are a classic application for IR detectors. LASER COMPONENTS manufactures detectors with various technologies: Pyroelectric detectors with integrated filters are very widespread. In order to measure gases very quickly or in a particularly small concentration, it is necessary for the detector to be particularly highly sensitive. Here, PbSe detectors are often used. They are also available immediately in a multichannel version.
“The needle in a haystack” is found using laser measurement methods: xInGaAs, InAs, and DLaTGS detectors are used for this purpose.
