About Infrared Light Detection
& the Use of Infrared Cameras
Infrared is an invisible light spectrum between the range of 0.75 to 1000 microns. Everything warmer than absolute zero (0 Kelvin or -275.15°C) emits energy within that range. The warmer the object, the brighter it appears in the infrared image via the lense of a infrared camera or thermal imaging camera. Yellows and reds (warm colors) represent a hot surface, white representing the hottest temperature. When the surface is cooler, the infrared image appears in darker colors such as blues or greens, black representing the coldest.
