Paper Abstract

All reflective zoom optical systems have advantages of no color aberration and lightweight which have a wide application prospects in space optical system. All reflective zoom optical systems, which have been designed, all use telephoto construction. And these systems have disadvantages of big obscuration and small field of view. So in order to satisfy of requests the wide spectrum and field of view of space optical system, this paper design a novel all reflective zoom optical system which uses anti-telephoto construction with 3 mirrors. Firstly, using the zoom theory of differential, the initial configuration with 2 zoom ratio was obtained. Then simulating and optimizing the system with Zemax that is software of the optical design, we get a novel all reflective zoom optical system. It has a smaller obscuration and bigger field of view than traditional reflective zoom optical system. At last, the image qualities of this system was evaluated and concluded. And the image qualities of this novel all reflective zoom system is well and the construction of the optical system is reasonable. It can be applied in space optical system.
