Infrared. A pseudocolor image of two people taken in long-wavelength infrared (body-temperature thermal) radiation. This false-color infrared space telescope image has blue, green and red corresponding to 3.4, 4.6, and 12 μm wavelengths, respectively. Infrared (sometimes called infrared light and IR) is … Visa mer Infrared (sometimes called infrared light and IR) is electromagnetic radiation (EMR) with wavelengths longer than those of visible light and shorter than radio waves. It is therefore invisible to the human eye. IR is generally … Visa mer In general, objects emit infrared radiation across a spectrum of wavelengths, but sometimes only a limited region of the spectrum is of … Visa mer Night vision Infrared is used in night vision equipment when there is insufficient visible light to see. Night vision devices operate through a process involving … Visa mer There is no universally accepted definition of the range of infrared radiation. Typically, it is taken to extend from the nominal red edge of the visible spectrum at 700 nanometers (nm) to 1 millimeter (mm). This range of wavelengths corresponds to a frequency range … Visa mer Sunlight, at an effective temperature of 5,780 kelvins (5,510 °C, 9,940 °F), is composed of near-thermal-spectrum radiation that is … Visa mer Infrared radiation is popularly known as "heat radiation", but light and electromagnetic waves of any frequency will heat surfaces that absorb them. Infrared light from … Visa mer The discovery of infrared radiation is ascribed to William Herschel, the astronomer, in the early 19th century. Herschel published his results in 1800 before the Visa mer WebbThere is a great interest in spectroscopic sensors in the near and middle infrared (NIR-MIR) wavelength regions (1 - 2.5 micrometers; 2.5 - 4.5 micrometers; 4 - 6 … http://support.flir.com/appstories/AppStories/R&D/Near_Infrared_(NIR)_cameras_EN.pdf how many boston red sox world series titles
