IR

English
Infra Red Radiation | Frequencies: (*) 300GHz – 430THz

Sources and Uses

  • Sun light (52.7% of the radiation power from the sun reaching earth is IR)
  • Astronomic objects emitting IR radiation only or in addition to other radiation
  • Every object on earth emits IR radiation
  • The human and animal body emit IR radiation
  • Thermal heating – electric heaters, bonfires, fires
  • IR lasers for fiber-optic and wireless communication
    • Far IR communication: 1.53 -1.56 microns, Near IR radiation–fiber telecommunication 0.7-1.4 microns 
  • Computer and multimedia accessories
  • Thermal imaging (an alternative to X-ray imaging) – TeraHz frequencies
  • Measuring and diagnostics in engineering
  • IR-operated weapons
  • Night-vision instruments
  • Meteorology, astronomy, spectroscopy
