2. (figuratively, not-comparable) Relating to very low energies or very large distances or time spans.
   • Secondly, as stated already by Osborne & Provenzale, pure k^(-α)-behaviour is impossible since there would have to be infinite power at zero frequency (this would correspond to an infrared catastrophe). 2000, Andreas Galka, Topics in Nonlinear Time Series Analysis: With Implications for EEG Analysis, →ISBN, page 176:
   • Although infrared divergences are of long-distance nature, they often play an essential role in the verification of the validity of the perturbative treatment of short-distance phenomena. 2010, Taizo Muta, Foundations of Quantum Chromodynamics: An Introduction to Perturbative Methods in Gauge Theories, 3rd edition, →ISBN, page 331:
   • Unless otherwise stated, we will be working in Euclidean space compactified to a sphere in order to avoid infrared problems. 1986, Luis Álvarez-Gaumé, “An Introduction to Anomalies”, in G. Velo, A. S. Wightman, editors, Fundamental Problems of Gauge Field Theory, →ISBN, page 97:

Meanings

1. (uncountable) The electromagnetic radiation of a wavelength longer than visible light, but shorter than microwave radiation, having a wavelength between 700 nm and 1 mm.
   • Collisions of these 'transparent' molecules with the molecules that do have absorption bands in the infrared can have a considerable influence on the intensities of the observed absorption bands. 1962, John Nelson Howard, Transmission of the Atmosphere in the Infrared: A Review, page 3:
2. (countable) A specific wavelength in this range.
   • Sonne has shown that by means of the luminous rays the temperature in the tissue may be raised to a higher degree than by the use of the infrareds. 1924, The American Review of Tuberculosis, page 110:
   • Exposure of spectral pieces at centimeters, millimeters, and infrareds, which provide a top steadiness of the dependence "MCW radiation vs. parameter Δt" and its interannual (seasonal) dynamics. 2009, Alexander Grankov, Microwave Radiation of the Ocean-Atmosphere: Boundary Heat and Dynamic Interaction:
3. (countable) A device that emits infrared radiation.
   • Additionally, infrareds tend to cook food faster so there's less time to render said fat. 2020, Jenny Dorsey, The Infrared Grill Master: Recipes and Techniques for Perfectly Seared, Deliciously Smokey BBQ Every Time:
   • In his room, he could install his infrareds without being discovered. 2000, Pete Fowler, Keeps, page 62:
   • Beams are the active counterparts of passive infrareds (PIRs). Since these are active infrareds, they require two parts: a transmitter and a receiver. 2007, Ed Morawski, Solving the Security Puzzle, page 79:
