Infrared (IR) is invisible radiant energy, electromagnetic radiation with longer wavelengths than those of visible light, extending from the nominal red edge of the visible spectrum at ~700nm (frequency 430 THz) to 1mm (300 GHz) (although from test data some people can see infrared up to at least 1050nm) in λP wavelengths. The visible region of the spectrum comprises photon energies of 36 to 72 kcal/mole, and the near ultraviolet region, out to 200 nm, extends this energy range to 143 kcal/mole. It can also be divided into five categories: near-, short-wavelength, mid-, long-wavelength and far-infrared. Optical isolators, also known as Faraday isolators, are magneto-optic devices that preferentially transmit light along a single direction, shielding upstream optics from back reflections. Infrared radiation, that portion of the electromagnetic spectrum that extends from the long wavelength, or red, end of the visible-light range to the microwave range. The near-infrared spectral region (also called IR-A) is normally understood to range from ≈ 700 to 1400 nm. When you work in IT, you should consistently try to expand your knowledge base.
