Infrared in a sentence

Carina Nebula in infrared light captured by the Hubble 's Wide Field Camera 3. Infrared astronomy is the branch of astronomy and astrophysics that studies astronomical objects visible in infrared (IR) radiation.

Infrared in relation to electromagnetic spectrum Natural infrared Sunlight, at an effective temperature of 5,780 kelvins, is composed of nearly thermal-spectrum radiation that is slightly more than half infrared.

The patent-pending Quantum Stealth material is able to hide a target as well being able to bend in ultraviolet, infrared and shortwave infrared.

In this method, the infrared sensor is placed at the tip of the pen, so that infrared cameras are placed at 1m distance away of the person.

Animals that detect infrared make use of small packets of water that change temperature, in an essentially thermal process that involves many photons (see infrared sensing in snakes ).

Atacama, Chile. citation Infrared astronomy is founded on the detection and analysis of infrared radiation (wavelengths longer than red light).

Consequently, infrared observatories have to be located in high, dry places or in space. citation Some molecules radiate strongly in the infrared.

Currently, the primary payload for the aircraft is the Israeli Aircraft Industries POP300 Plug-in Optical Payload which consists of a forward-looking infrared camera, a daytime TV camera with a selectable near-infrared filter and a laser pointer.

Directly heated glass gives off enough infrared radiation to turn the vanes, but glass blocks much of the far-infrared radiation from a source of warmth not in contact with it.

HgCdTe is sensitive to infrared light and can be used as an infrared detector, motion detector, or switch in remote control devices.

Infrared astronomy began in the 1830s, a few decades after the discovery of infrared light by William Herschel in 1800.

Infrared controllers project a grid of infrared beams inserted into the frame surrounding the monitor screen itself, and detect where an object intercepts the beams.

Infrared Like radio and microwave, infrared also is reflected by metals (as is most EMR into the ultraviolet).

Missiles that use infrared seeking are often referred to as "heat-seekers", since infrared (IR) is just below the visible spectrum of light in frequency and is radiated strongly by hot bodies.

Nonlinear two-dimensional infrared spectroscopy is a technique that has become available with the development of femtosecond infrared laser pulses.

On the surface of Earth, at far lower temperatures than the surface of the Sun, almost all thermal radiation consists of infrared in mid-infrared region, much longer than in sunlight.

Photographs taken with infrared light through night vision devices always show very bright pupils because, in the dark, the pupils are fully dilated and the infrared light is not absorbed by any ocular pigment.

Regions within the infrared 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.

Remote controls and IrDA devices use infrared light-emitting diodes (LEDs) to emit infrared radiation that is focused by a plastic lens into a narrow beam.

The infrared portion of the electromagnetic spectrum is usually divided into three regions; the near-, mid- and far- infrared, named for their relation to the visible spectrum.
