摘要
与连续变焦光学系统相比,红外两档变倍光学系统具有结构简单、成像质量好、装调容易等特点,介绍了红外两档变倍光学系统的设计方法,并举例设计了一种方案合理、成像质量好的红外两档变倍光学系统,对光学系统的0视场、0.5视场、0.71视场、0.866视场和1视场成像质量进行了分析,给出了各个视场的分析结果,同时分析了温度变化对光学系统的影响,分析表明设计结果能够较好地满足实际工程需要。
Compared with the continuous zoom system, infrared switch-zoom optical system had many advantages, such as simple structure, prefect imaging quality and easy fixing. In this paper, the design method was introduced. And an example was given, The analysis results for various fields were presented and the thermal effect on optical system was analyzed.The results show that the design is reasonable and the imaging quality is good.
