摘要:在七片照相物镜结构的基础上，利用zemax光学设计软件，通过缩放和建立评价函数操作数的设置，设计一个焦距为25mm，全视场为18.18°，F数为1.2的微光镜头，以及在设计过程中遇到问题思考和最终问题的解决，最后将设计完成，并对设计的镜头进行分析并得出结论。设计最终得到40lp/mm中心视场的MTF为0.88,在0.8视场子午光线MTF为0.80，弧矢光线为0.85.

Abstract: Base on the seven pieces of photographic lenses’ structures, taking advantage of the ZEMAX Optical Design Program to design a Glimmer of lens which the focal distance is 25mm , the full FOV is 18.18° and the F is 1.2 through zooming and installing the merit function. The project will be accomplished through thinking and solving the problems in the design process. Through analyzing the design of the lens we can draw a finally conclusion that at the 40lp/mm center area of FOV, the MTF is 0.88 and at the 0.8 FOV, the meridio nal ray MTF is 0.78 and the sagittal ray is 0.85.
