本文主要讨论变焦距光学系统的凸轮误差、各移动组焦距误差和安装位置误差对变焦距物镜光学像面位置稳定性的影响,以及如何调整移动组的起始位置使三个焦面位置一致。
This paper mainly discusses the influence of the cam error of the zoom optical system, the focal length error of each moving group and the installation position error on the position stability of the optical image plane of the zoom lens, and how to adjust the starting position of the moving group so that the positions of the three focal planes are the same.
