摘　　要：为了更好地选择一个合适的的辅助物镜,基于辅助物镜的工作原理,从理论推导和实验仿真两方面出发,对常见双胶合形式的辅助物镜进行了结构优化设计。根据设计要求,合理选择辅助物镜的初始结构,并从理论上推导了各类像差。基于初始结构和优化目标,利用光学设计软件OSLO对2种形式的辅助物镜进行了结构优化和像差分析。之后对于创新型双胶合-厚弯月型辅助物镜进行设计优化,以文献中相似透镜的结构参数为该设计的初始结构,利用OSLO光学软件及设计经验,对其进行结构优化、像差分析及矫正。对2种形式的辅助物镜进行对比分析的结果表明,2种结构形式的辅助物镜经过优化后,其参数均能满足设计要求,但双胶合-厚弯月型的辅助物镜更适用于大像面的光学系统。In order to better choose a suitable auxiliary objective lens,this article is based on the working principle of the auxiliary objective lens,starting from both theoretical deduction and experimental simulation,firstly,the structure optimization design of the common double glued auxiliary objective lens is carried out.According to the design requirements,the initial structure of the auxiliary objective lens was reasonably selected,and various aberrations were theoretically deduced.Finally,based on the initial structure and optimization goals,the optical design software OSLO is used to optimize the structure and aberration analysis of the two forms of auxiliary objective lenses.Afterwards,the design of the innovative double cemented-thick meniscus auxiliary objective lens was optimized.The structural parameters of the similar lens in the literature were used as the initial structure of the design.OSLO optical software and design experience were used to optimize the structure and analyze aberrations.And correction.Finally,the two types of auxiliary objectives are compared and analyzed.The results show that the parameters of the two types of auxiliary objectives after optimization can meet the design requirements,but the double-bonded-thick meniscus type auxiliary objective is more suitable for large images.The optical system of the surface.
