The dynamics of waveguides in the midwave infrared (MWIR, 3 μm–8 μm) and long wave infrared (LWIR, 8 μm–15 μm) is expected to be different. In the MWIR, mode guidance is tighter, leading to higher peak ... Mid-wave infrared: 3 to 5 μm (defined by the atmospheric window and covered by indium antimonide, InSb and mercury cadmium telluride, HgCdTe, and partially by lead selenide, PbSe). Long-wave infrared: 8 to 12, or 7 to 14 μm (this is the atmospheric window covered by HgCdTe and microbolometers). Ver mais 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 … Ver mais In general, objects emit infrared radiation across a spectrum of wavelengths, but sometimes only a limited region of the spectrum is of … Ver mais 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 the conversion of ambient light photons into electrons that are then amplified … Ver mais 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) … Ver mais Sunlight, at an effective temperature of 5,780 kelvins (5,510 °C, 9,940 °F), is composed of near-thermal-spectrum radiation that is … Ver mais Infrared radiation is popularly known as "heat radiation", but light and electromagnetic waves of any frequency will heat surfaces … Ver mais The discovery of infrared radiation is ascribed to William Herschel, the astronomer, in the early 19th century.
