    • Infra-red affected by infrared radiation; as, infrared detector; infrared film.
    • Infra-red (Physics) Lying outside the visible spectrum at its red end; -- said of rays having a longer wavelength (and thus less refrangible) than the extreme red rays, specifically those electromagnetic waves having a wavelength of between 700 nanometers and 1 millimeter.
    • Infra-red relating to, using, or producing infrared radiation.

Infra-, + red,


In literature:

This absorbed radiation is chiefly known as infra-red energy, which does not arouse the sensation of light.

I'll cut out the visible spectrum before the flash, and convert and reconvert the infra-red.
"Skylark Three" by Edward Elmer Smith
A white-speckled grey filled the infra-red screen, radiation from the still warm sand and stone.

The infra-red part of the spectrum, investigated by Langley, Abney, and Knut Angstrom, reaches perhaps no definite end.

In science:

Also, as αs reduces so real emission is less likely and the Sudakov suppression is less effective in steering QT away from the infra-red.
Diffractive Higgs production: theory
Discussion of the infra-red sensitivity would not be complete without returning to the issue of the unintegrated gluon density.
Diffractive Higgs production: theory
Since BL are not interested in suppressing radiation, they do have a problem with the infra-red since there is no Sudakov factor.
Diffractive Higgs production: theory
The underlying theory has been explained and the various sources of uncertainty highlighted with particular emphasis on the sensitivity of the predictions to gluon dynamics in the infra-red region.
Diffractive Higgs production: theory
Knox et al. 2004) have been carried out testing how well one can hope to extract vpec via the kSZ effect, including the effects of known systematic errors and noise sources, e.g., interstellar dust emission, infra-red (IR) galaxies, radio sources, imperfect bulk velocity, etc.
