Infrared (or IR) is the part of the electromagnetic spectrum consisting of wavelengths between 750 nm and 1 mm. It is commonly referred to as "heat", as temperatures produced by combustion, electrical discharge, biochemical, or other processes typically produce an infrared signature.
Lifeforms and equipment that could see infrared could usually detect an infrared source in a darkened area without the assistance of artificial lighting.
