一、修订背景在精密计量领域,传统的透镜焦距测量采用光具座来实现。光具座是光学零件生产和光学系统调试过程中的一种通用仪器。光具座的用途很广,除了用于测量透镜的焦距、后顶焦距外,它还被用于检测光学系统的分辨力和像质,测定平行平板的平行差以及棱镜的角度误差等。可以说光具座是光学实验室最为常 First, the revised background In the field of precision measurement, the traditional lens focal length measurement using optical bench to achieve. Optical pedestal is a universal instrument used in optical parts manufacturing and optical system debugging. Optical bench is widely used, in addition to measuring the focal length of the lens, the top of the focal length, it is also used to detect the resolution and quality of the optical system to determine the parallel plate parallel to the poor and the prism angle error. Optical bench can be said that the most common optical laboratory
