notability established

The subject seems notable to me, judging e.g. by Google. However sources are completely missing and need to be added. Will also link this article with CO2 sensor, it is orphaned right now. Sorted as part of the Notability wikiproject. --B. Wolterding 17:54, 14 July 2007 (UTC)[reply]

meaning of non-dispersive

I wonder if naming the detection as "non-dispersive" is related to the means of spectral selection, that is, by a narrow-band interference filter, instead of by using a dispersive element such as a prism (or a diffractive element such as a grating). What the head says is, "since the infrared energy is allowed to pass through the atmospheric sampling chamber without deformation". I think that "deformation" is not a term frequently encountered in optical discussions. I think, at the least, the subject of "infrared energy deformation" needs to be expanded on. --AJim (talk) 03:43, 3 June 2015 (UTC)[reply]
