| Abstract: | 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. |
