为了满足军用瞄准镜使用中需要配备护眼罩和防毒面具等的要求,需要目镜光学系统的出瞳距离较长.分析了长出瞳距目镜的光学特性与像差特点,提出了正、正、负三镜组的结构型式.根据像差理论,采用解析法推导了光焦度分配公式.利用光学设计软件ZEMAX设计了长出瞳距目镜,系统焦距为20 mm,出瞳直径为5 mm,视场角为40°,出瞳距离为40 mm,相对镜目距为2.设计结果表明,采用该方法设计的目镜在40 lp/mm处各个视场的传递函数均在0.2以上,满足目视光学仪器的使用要求.

To meet the requirement of wear eye protection and gas mask when using the military sighting telescope, the exit pupil distance of eyepiece is needed to be longer than the other. The optical characteristics and aberration characteristics of eyepiece with long exit pupil distance were analyzed, and the configuration of positive, positive, and negative three lens groups was proposed. According to the aberration theory, the optical power distribution formula was derived by analytical method. The eyepiece with long exit pupil distance was designed with optical design software ZEMAX, the focal length was 20 mm, exit pupil diameter was 5 mm, view angle was 40°, exit pupil distance was 40 mm, and relative eye clearance was 2. Designing results show that the MTF of every field above 0.2 in 40 lp/mm satisfy the application requirements of visual optical instrument.
