摘要
保护玻璃的平行差对一般观察光学仪器成像影响不大,但瞄准类光学仪器保护玻璃楔形平行性误差会引起系统色差及光轴的变动,最小焦距误差会改变系统总焦距。通过对平行平板光学玻璃楔形平行差、最小焦距及色差的分析计算提出了影响后面光学系统成像质量的因素。并通过对美国90型搜索潜望镜保护玻璃水平及垂直光学截面内平行差的矩阵计算,为光学平晶的设计提供了依据,也为制造过程指标控制给出了测量方法。
The wedge angle deviation of protective glass has little effect on the imaging of general observing optical instrument. The system color aberration and optical axis were changed by the wedge angle deviation of protective glass. The total focus of the system was changed by the least focus. The affecting factors of imaging quality were presented by the analyse of the parallel error, the least focus of plant and the color aberration. The matrix of the parallel error in plane and upright section of the American 90 searching periscope was calculated.
