摘　　要：针对后置式投影亮分划光学系统在某型微光镜中应用时出现零位走动量超差问题,通过分析该类微光瞄准镜的零位稳定性机理以及开展冲击试验,发现零位走动量超差的主要原因是射击过程中光学系统组合棱镜发生转动,采取将组合棱镜外形尺寸和安装尺寸公差优化方法,使二者间隙小于0.02 mm,最终微光镜的零位走动量(Δd)小于0.26 mil,满足系统技术指标规定Δd≤0.7 mil要求。给出了同类瞄准镜在设计和生产中对零位走动量控制的关键点及问题解决方案,为提高瞄准镜零位稳定性提供了有效分析依据。Aiming at the variational momentum of the zero position overshoot problem when rear mounted reticle with projected brightness was applied in a certain type of low-light-level(LLL)sight mirror,the zero stability mechanism of this kind of LLL sight mirror was analyzed.The impact test shows that the main reason for the variational momentum of the zero position overshoot is the rotation of the combined prism in the optical system during shooting.The overall size and mounting size tolerances of the combined prism were optimized,the gap between the two sizes was less than 0.02 mm,and the variational momentum of the zero position(Δd)of the LLL sight mirror was less than 0.26 mil,meeting the requirements ofΔd≤0.7 mil specified in the system technical specifications.The key points and solutions of variational momentum of the zero position control in design and production of similar scope were given,which provided an effective analysis basis for improving the zero stability of the scope.
