Design of Mechanically Athermalized Longwave Infrared Optical System with Wide Field of View and Large Relative Aperture
摘要
研究了大视场大相对孔径长波红外机械无热化光学系统的设计， 设计了8 ～ 12 m波段内F数为0.8、温度在－40 ～ 60℃范 围内无热化的光学系统。结果表明，该系统结构简单，像质好，在空间频率20 lp/mm处的 光学传递函数值大于0.5。
Abstract
The design of mechanically athermalized longwave infrared optical systems with wide field of view and large relative aperture is studied. An optical system with the F number of 0.8 is designed for the waveband of 8 to 12 m. It is athermalized in the temperature range -40℃ to 60℃. The analysis results show that the optical system is simple in structure and good in imaging quality. It has an optical transfer function greater than 0.5 at the spatial frequency of 20 lp/mm.
