Infrared light, the light below red, is radiation similar to visible light with however longer wavelength and therefore lower energy. Infrared technology exploits this light for a widely range of applications such as thermal imaging, chemical and biologic analysis. The most important applications will be presented and discussed. The detection of infrared light necessitate appropriate detector and optical system that are very different from the components used in visible system. The fabrication of infrared detector arrays is quite challenging due to the low energy of the light to be detected. Two technologies, the cooled detectors and the uncooled detectors, have been developed for different applications. These two technologies will be presented and compared. Conventional optical system based on oxide glasses is completely opaque in the middle infrared region and cannot be used for thermal imaging. Very few materials are transparent in the 2nd atmospheric window of 8-12 µm, the preferred window for thermal imaging. These materials will be presented and compared. "
