摘　　要：为满足枪瞄镜在军品中的需求,设计了一套可实现8~32倍连续变倍的枪瞄镜。阐述了本套枪瞄镜的设计思路与设计方法。首先根据设计指标,对物镜组,目镜组以及中继转像镜组进行指标分解计算。随后对物镜、目镜以及整个枪瞄系统进行高斯光学设计,确定整体系统的复杂程度及光学结构参数。然后根据高斯结构设计结果,进行初始结构选择,依据设计指标选择优化操作数,进行系统优化。最后完成整体系统设计与优化结果的评估。最终的设计结果中:枪瞄镜物镜口径56 mm,目镜口径50 mm,系统总长410 mm;低变倍比组态畸变2.4%;高变倍比组态的轴上弥散斑半径6.2μm,轴外弥散斑半径8.3μm,像差指标符合设计要求,有效地解决了产品加工成本较高的问题。In order to meet the demand of gun sight in military products,a set of gun sight which can realize 8×~32×continuous magnification is designed.The design idea and method of the gun scopes are described in detail.Firstly,according to the design index,the objective lens group,eyepiece group and relay mirror group are decomposed and calculated.Then,the Gauss optical design of the objective lens,the eyepiece and the whole gun aiming system is carried out to determine the complexity of the whole system and the optical structure parameters.Then,according to the results of Gauss structure design,the initial structure is selected,and the optimization operand is selected according to the design index to optimize the system.Finally,the evaluation of the overall system design and optimization results is completed.In the final design results,the objective lens of the gun sight has an aperture of 56 mm,the eyepiece has an aperture of 50 mm,and the total length of the system is 410 mm;the aberration of the low magnification group is 2.4%,the on-axis diffuse spot radius of the high magnification group is 6.2μm,the off-axis diffuse spot radius is 8.3μm,and the aberration index meets the design requirements.
