WebIntroduction. Infrared waves are commonly referred to as thermal or heat waves. These waves consist of heat-inducing properties with the wavelength of infrared waves ranging from 710 mm to 1mm. At times, these waves are categorised into far-infrared or near-infrared rays. Mostly, these waves are used in applications for producing large amounts ...

There are four main properties that characterize thermal radiation (in the limit of the far field): • Thermal radiation emitted by a body at any temperature consists of a wide range of frequencies. The frequency distribution is given by Planck's law of black-body radiation for an idealized emitter as shown in the diagram at top. • The dominant frequency (or color) range of the emitted radiation shifts to higher frequencies as the temperature of the emitter increases. For example, a red hot o… Short-wavelength infrared SWIR, IR-B DIN: 1.4–3 μm 100–214 THz 413–886 meV 2,070–966 K (1,797–693 °C) Water absorption increases significantly at 1,450 nm.

It is therefore invisible to the human eye. IR is generally … See more In general, objects emit infrared radiation across a spectrum of wavelengths, but sometimes only a limited region of the spectrum is of interest because sensors usually collect radiation only within a specific bandwidth. Thermal infrared radiation also has a … See more Night vision Infrared is used in night vision equipment when there is insufficient visible light to see.
