infrared radiation

Infrared radiation covers from ~750 nm - 1000 µm on the electromagnetic spectrum, depending on the classification standard. It has been further sub-divided into near-infrared (750 - 1400 nm), short-wave (1.4 - 3.0 µm), mid-wave (3.0 - 8.0 µm), long-wave (8.0 - 15.0 µm), and far-infrared (15 - 1000 µm).
