| 摘 要： | 建立了红外光学系统无热化设计与变焦距镜头的关系，即可把红外光学系统无热化设计过程看成是广义变焦过程，介绍了设计广义变焦距镜头的过程，并进行了相关的理论推导，设计广义变焦距镜头的过程可分为以下四个步骤；（1）在常温下的满足像质要求的系统内设定变焦位置，（2）建立不同温度状态下的玻璃库；（3）建立不同变焦位置的联系；（4）温度分析与加入消除热效应因素。

| Abstract: | The relationship between athermalizing infrared optical system and zoom lens is established. The process of designing a athermalizing infrared optical system could be regarded as a process of generalized zooming. The process of designing a generalized zoom lens is described in detail, and the correlative principles are deduced. This process consists of four steps, which are setting zoom positions in the system that satisfies image performance demand at normal temperature, entering private glass catalog at different temperatures, establishing relationship between different zoom positions and analyzing thermal effect, then adding factor that could eliminate thermal effect. |
