1.前言众所周知,在光学系统的制作误差中,最难办的就是系统的偏心误差了。光学系统的偏心问题,绝不是只靠追求单片透镜的精度就可以解决的。这是因为安装透镜的镜筒加工好坏,以及将单片透镜装配到镜筒里的过程中,操作者的细致程度等等,都给最终的精度带来很大影响。一方面,存在偏心的光学系统中,一般说都产生偏心所特有的非对称性像差,通过这种现象可以确定偏心的存在。但是,只要查不清楚究竟是光学系统
1. Preface As we all know, in the production of optical system error, the most difficult to do is the system of eccentric error. Eccentricity of the optical system, by no means the pursuit of single-lens accuracy can be solved. This is due to the fact that the lens-mounted lens barrel is well-formed and the assembly of the one-piece lens into the lens-barrel, the operator’s meticulousness, etc., have a great impact on the final accuracy. On the one hand, in the case of an optical system with eccentricity, asymmetric aberrations peculiar to the eccentricity are generally generated, by which the existence of eccentricity can be determined. However, as long as the investigation is not clear what is the optical system
