With the development of infrared detection technology,cryogenic optical technology aiming at reducing the background radiation has become the main way to improve the development of infrared detection technology.The key factors of infrared cryogenic optical technology are expounded,such as cryogenic optical system configuration choices,optical and mechanical structural design,selection of optical system materials and design of optical system cooling scheme in cryogenic optical processing.Two application examples of infrared cryogenic optics are introduced,such as infrared remote sensing camera and infrared space telescope.At last,the application of cryogenic optics in airborne infrared system is prospected.
