摘　　要：双波段鱼眼红外光学系统可以获取中波和长波两波段的图像信息，同时由于其大视场的特性，可以大大增加目标信息获取范围。根据光学系统的设计要求对光学系统进行了设计，全视场196°，4.4~5.4μm/7.8~8.8μm波段内清晰成像，考虑到冷光栏的制冷效应，F#严格与冷光栏匹配，达到100%的冷光栏效应。推导了大视场被动消热差公式，通过对玻璃材料的优化选择，达到了双波段消热差，所设计的光学系统结构相对简单，成像质量较好，系统各个波段在-40~60℃的工作温度下实现了消热差，满足使用需求。
The dual-band infrared optical system can track the band informantion stretch from mid-wave infrared to long-wave infrared, which can greatly improved the information acquisition. A dual-band infrared optical system based on the compact principle was designed, the optical system can imaging clearly continuous from 4.4-8.8μm/17.8-8.8μm, the F# strictly matched with cold light bar that the cold light bar effect reached 100%. While the system using the passive athermal methods to get rid of temperature compensation problem and finally realized the dual-band of athermalization. The result shows that： the design of the system structure is relatively simple, and can get stable good imaging quality in continuous bands from -40℃ to 60℃, satisfying the requirements of a standard infrared thermal imager.
