| Abstract: | According to the specific requirements of infrared optical system that was used in Unmanned Air Vehicle, in this paper, an infrared optical system for 8 to 12 μm waveband is designed based on the VOx 320×240 FPA with the distance between pixels of 38 μm. By using binary surface, aspheric surface and new material of GaASIR2, the technology of optical passive athermalization is applied to eliminate the influence of temperature effect at －80℃ to ＋120℃.The system has the F-number of 1, the effective focal length of 17.5 mm, the field of view of 40°×30°and the total length of 46 mm. Compared with other like products, the system has the merit of less optical element, smaller volume, lighter weight and higher imaging quality. |
