Talk:Far infrared

Will Fix
I'm getting my PhD in chemistry and will rewrite this page to higher standards as soon as I get a chance including graphics, valid peer reviewed references and better scientific writing.Eframgoldberg (talk) 05:11, 23 November 2012 (UTC)


 * Thanks. One of the problems you will face is that there is great variance in the basic definition, for example:


 * 10-1000 µm
 * Merriam-Webster's Dictionary
 * http://www.merriam-webster.com/dictionary/far-infrared


 * 2-50 microns (=µm)
 * The American Heritage® Science Dictionary


 * about 3.0–1000 µm
 * Three sources (all from Elsevier -- same editorial staff?)
 * Dorland's Medical Dictionary for Health Consumers
 * Miller-Keane Encyclopedia and Dictionary of Medicine, Nursing, and Allied Health
 * Saunders Comprehensive Veterinary Dictionary


 * There's a rough correspondence to IR-C
 * "between 3000 and 1 * 10^6 nm (or 1 mm) is referred to as IR-C"
 * Millodot: Dictionary of Optometry and Visual Science


 * All but the first of these are collected at http://medical-dictionary.thefreedictionary.com/Far-:infrared.

Sections to Expand
I added the first two application sections: astronomy and medicine (although the medicine information was already present). I'll work on finding more applications, but there's still very little theory in this article. -- CaptainTickles (talk) 07:07, 28 January 2013 (UTC)


 * I would like to expand on the medicinal applications of IR therapy. I feel that the sentence "However, larger and more-rigorous studies are needed to confirm these results" is a matter of opinion.  Is anyone opposed to removing this sentence and adding some more factual information?  Atsmith227 (talk) 16:58, 15 January 2014 (UTC)


 * I added a small section on the use of far infrared in human body sensors.198.58.150.217 (talk) 20:29, 7 August 2015 (UTC)

I added a brief section on therapeutic modalities as this seems to be an emerging option for medical treatment. It's my first time adding anything on wikipedia and would appreciate any feedback. Thanks. (JMM54321) 26 January 2017

Diagram mistake
This diagram at the beginning of the article made by Biomatscience is missing UV spectrum between xray and visible spectrum and thus is not aaccurate. 213.149.61.225 (talk) 00:01, 1 December 2018 (UTC)


 * That diagram is kind of a train wreck actually. It expands out the range typically called "long-wavelength infrared", but this article is about far infrared. It captions it "Resonant frequency", but then gives the numeric range not in frequency but in wavelength. What is "resonant frequency" even supposed to mean on this diagram? This thing is way worse than useless, would be better to just delete it. 66.76.242.44 (talk) 23:57, 23 September 2019 (UTC)
 * I found a much better image on a Nasa website, but I cant figure out how to format it so it'll look well.
