摘　　要：对于三片式照相物镜的设计,首先,根据设计要求从已有专利、文献中选取一个与其相近的系统作为原始系统。其次,利用Zemax光学设计与仿真软件对初始结构进行整体缩放,直至符合设计要求值。最后,分别通过优化镜头诸面的面形参数及调制传递函数(MTF)曲线对像差进行优化与校正。得到一款焦距为30 mm,半视场角为25°,F数为4的三片式照相物镜。该镜头由1个弯月凸透镜、1个双凹透镜和1个双凸透镜组成。设计结果表明:整个光学系统为对称式结构,结构简单且紧凑,总轴长度为33.83 mm,光学系统的弥散斑较小,最大畸变小于0.017。For the design of the triplet photographic lens,firstly,according to the design requirements,select a similar system from existing patents and documents as the original system.Secondly,the initial structure is scaled by Zemax optical design and simulation software until it meets the design requirements.Finally,the aberration is optimized and corrected by optimizing the surface shape parameters and modulation transfer function(MTF)curve of the lens.A three-piece photographic objective with a focal length of 30 mm,a half-field angle of 25°and an F number of 4 is obtained.The lens consists of a meniscus convex lens,a biconcave lens and a biconvex lens.The design results show that the whole optical system is symmetrical,simple and compact,with a total axis length of 33.83 mm,and the optical system has a small speckle and the maximum distortion is less than 0.017.
