摘　　要：为设计一套焦距17～1 700mm的长焦距、超高倍率变焦距光学系统,首先在合理选择初始结构基础上,通过比较高斯光学计算结果找出高斯解对系统性能的影响规律,从而确定系统的关键参量;然后通过分析各组元相对孔径和像差特点选定结构形式,并进行系统像差的校正和优化.设计结果系统光学总长760mm,各焦距位置全视场50lp/mm处MTF>0.3,各项指标满足系统要求.In order to design an optical system with focal length range from 17 to 1 700 mm,a proper initial optical layout is selected first,the rule of system performance influenced by Guassian solution is found through comparing Guassian optical calculation results,and the key parameters of the system are selected.Then the configuration of each assembly is chosen through analyzing the relative aperture and characteristics of aberrations,and the system aberration is corrected and balanced.The total track of the result lens is 760 mm,the modulation transfer functions at 50 lp/mm for each zoom configurations and all fields of view are greater than 0.3,and all indexes satisfy the command of system.
