摘要
为了保证补偿器的技术要求,既:偏心差小于4″,空气间隔公差小于或等于0.002mm。本文首先通过对非球面加工、检测及装调中应用的补偿法和偏心原理的介绍,阐述了非球面补偿器的结构设计以及装调原理;并进行了非球面主镜补偿器的装调误差分析。产品实际装调结果补偿器偏心差为1.76″,空气间隔公差0.002mm。验证了补偿器的结构设计与装调原理的正确性和实用性。
In order to guarantee the technical requirements ofa compensational device ： centering deviation less than 4＂, the tolerance of air interval in a lens less than 0.002mm, By introducing the compensational method and eccentric method in fabrication, testing, alignment and adjustment of aspherical surface, a structural design and method of alignment and adjustment ofa compensational device is expatiated in this article, and error ofa compensational device is analyzed. The result of production of centering deviation of a main mirror in a camera is 1.76＂ , the tolerance of air interval in a lens is 0.002mm, which approving the correctness and practicability of the principle of structural design and method of alignment and adjustment of a compensational device.
