Mirror lens of mapping camera is the important component

which can guarantee mapping camera to fulfill the mapping task with high precision. It’s performance will effect directly the imaging quality of the mapping camera. In order to gain the mapping camera with high imaging quality

the design of mirror lens is issued from the choice of materials

the decision of structure

the analysis of performance and so on. By compared

ZTC4 is selected as the material for mirror lens finally

and combination format is adopted that components with mirrors are assembled in the thin shell with stiffeners. Optical-mechanical structure with good overall performance is obtained though the static and dynamic mechanical analysis by PATRAN/NASTRAN. The geometric tolerance requirements are given

the processing methods of thin shell are developed

and the assembly process of one component and main mirrors lens is discussed.
