Considering the combat demands of an individual soldier and focusing on the poor imaging quality and very short exit pupil distance of current transmission sniper rifle scopes, a long-eye distance high-precision imaging sniper rifle scope is designed. Based on the design indices of the system, the objective and eyepiece sets are decomposed and the optical focal degree is calculated. The optical path of the scope is designed using ZEMAX software. The objective and eyepiece sets of the scope adopted a telecentric optical path. The magnification of the system is 10^×, the diameters of the incoming pupil and exit pupil are 50 mm and 5 mm, respectively, the field of view angle is 2.2°, the distance of the exit pupil is 87.89 mm, and the length of the mechanical cylinder is 403.76 mm. The design results show that the imaging quality of the objective lens and ocular lens is excellent. Moreover, the modulation transfer function value of the whole optical path after docking is greater than 0.85 at Nyquist frequency of 16.67 lp/mm, which meets the requirements of a military sniper rifle scope.
