The NASA Infrared Telescope Facility ( NASA IRTF ) is a telescope optimized for use in infrared astronomy and located at the Mauna Kea Observatory in Hawai ' i. It was first built to support the Voyager missions and is now the USA national facility for infrared astronomy, providing continued support to planetary, solar neighborhood, and deep space applications.

Infrared technology is low-cost and has the advantage of being allowed aboard.

Infrared radiation is absorbed by greenhouse gases, which in turn re-radiate much of the energy to the surface and lower atmosphere.

Infrared is also used to observe distant, red-shifted galaxies that were formed much earlier in the history of the universe.

Infrared light is absorbed at many wavelengths by water vapor in the Earth's atmosphere, so most infrared telescopes are at high elevations in dry places, above as much of the atmosphere as possible.

" Infrared grade " fused quartz ( tradenames " Infrasil ", " Vitreosil IR " and others ) which is electrically fused, has a greater presence of metallic impurities, limiting its UV transmittance wavelength to around 250 nm, but a much lower water content, leading to excellent infrared transmission up to 3. 6 μm wavelength.

Infrared searches are more useful for finding more distant ( higher redshift ) clusters.

Using newer and more powerful infrared telescope technology, able to detect brown dwarfs as cool as 150 kelvins out to a distance of 10 light-years from the Sun, preliminary results from the Wide-field Infrared Survey Explorer ( WISE survey ) have not, to date, detected Nemesis, although the analysis of the full survey is not yet complete.

Infrared receivers also tend to have a more or less limited operating angle, which mainly depends on the optical characteristics of the phototransistor.

Infrared light, rather than visible light is used more commonly, because optical fibers transmit infrared wavelengths with less attenuation and dispersion.

Infrared observation has shown there are no bodies of three or more Jupiter masses in this system.

Infrared satellite imagery can be used effectively for tropical cyclones with a visible eye pattern, using the Dvorak technique, where the difference between the temperature of the warm eye and the surrounding cold cloud tops can be used to determine its intensity ( colder cloud tops generally indicate a more intense storm ).

It contains more than 20 major instruments and devices including a High-Resolution Mass Spectrometer, Infrared Spectrometer, X-Ray Quadrupole Diffractometer, Laser Raman Spectrometer, FT-IR Spectrometer, and others.

Infrared light mainly causes thermal damage to the retina at near-infrared wavelengths and to more frontal parts of the eye at longer wavelengths.

The pod is limited in being primarily a daylight / clear-weather system, and is being slowly replaced by the more capable Thomson-CSF PDLCT (" Pod de Designation Laser a Camera Thermique " / Laser Designation Pod with Infrared Camera ") and Thales Damocles, which has a FLIR.

The Infrared Optical Telescope Array ( IOTA ) began with an agreement in 1988 among five Institutions, the Smithsonian Astrophysical Observatory, Harvard University, the University of Massachusetts Amherst, the University of Wyoming, and MIT / Lincoln Laboratory, to build a two-telescope stellar interferometer for the purpose of making fundamental astrophysical observations, and also as a prototype instrument on which we could perfect techniques which could later lead to the development of a larger, more powerful array.

The Wii Remote has a very accurate Infrared Light tracking camera.

* AIRS — Atmospheric Infrared Sounder — measures atmospheric temperature and humidity, land and sea surface temperatures.

Satellite measurements made in 1999 with the Wide Field Infrared Explorer showed that the brightness of Altair fluctuates slightly, varying by less than a thousandth of a magnitude.

The Spacelab Infrared Telescope ( IRT ) was also flown on the mission.

The Spitzer Science Center ( SSC ), part of the Infrared Processing and Analysis Center located on the Caltech campus, is the data analysis and community support center for NASA's Spitzer Space Telescope.

Infrared spectroscopy and mechanical strain as a function of temperature are valuable diagnostic tools for diagnosing such problems.

Infrared EMR interacts with dipoles present in single molecules, which change as atoms vibrate at the ends of a single chemical bond.

Infrared radiation in the spectral distribution of a black body is usually considered a form of heat, since it has an equivalent temperature, and is associated with an entropy change per unit of thermal energy.

* Many other forms of spectroscopy also rely upon Fourier Transforms to determine the three-dimensional structure and / or identity of the sample being analyzed, including Infrared and Nuclear Magnetic Resonance spectroscopies.

Infrared ( IR ) light is electromagnetic radiation with longer wavelengths than those of visible light, extending from the nominal red edge of the visible spectrum at 0. 74 micrometres ( µm ) to 300 µm.

Infrared light is emitted or absorbed by molecules when they change their rotational-vibrational movements.

Infrared light is used in industrial, scientific, and medical applications.

Infrared imaging cameras are used to detect heat loss in insulated systems, to observe changing blood flow in the skin, and to detect overheating of electrical apparatus.

Infrared spectroscopy ( IR spectroscopy ) is the spectroscopy that deals with the infrared region of the electromagnetic spectrum, that is light with a longer wavelength and lower frequency than visible light.

Infrared spectroscopy exploits the fact that molecules absorb specific frequencies that are characteristic of their structure.

Infrared sensing in snakes depends on a kind of natural thermal imaging, in which tiny packets of cellular water are raised in temperature by the infrared radiation.

Infrared LEDs are also used in the remote control units of many commercial products including televisions, DVD players, and other domestic appliances.

Infrared light reveals the dense open cluster forming at the heart of the Orion nebula.

The two kinds of wireless technologies used for WPAN are Bluetooth and Infrared Data Association.

Infrared Data Association ( IrDA ) uses infrared light, which has a frequency below the human eye's sensitivity.
