infrared

An invisible band of radiation at the lower end of the visible light spectrum. With wavelengths from 750 nm to 1 mm, infrared starts at the end of the microwave spectrum and ends at the beginning of visible light. Infrared transmission typically requires an unobstructed line of sight between transmitter and receiver.

Widely used in most audio and video remote controls, infrared transmission is also used for wireless connections between computer devices (see IrDA) and a variety of detectors (see IR detector). See IR remote control and IRED.

Infrared in the Spectrum
The infrared band comes after the microwave range and ends at visible light.


infrared
the part of the electromagnetic spectrum with a longer wavelength than light but a shorter wavelength than radio waves; radiation with wavelength between 0.8 micrometres and 1 millimetre

infrared [¦in·frə¦red]
(electromagnetism)
Pertaining to infrared radiation.

(electronics)infrared - (IR) Electromagnetic waves in the frequency range just below visible light corresponding to radiated heat. IR waves can be generated by a kind of LED and are often used for remote controls for televisions etc. and in some docking stations.
