光学仪器,不论是照相系统、显微系统、望远系统抑或多光束折反系统,占较大比例的是球面光学零件。随着仪器性能的改善、功能的扩大,对这些球面零件的面形和曲率半径的准确度要求也越益提高,并且,球面零件曲率半径随所处仪器不同其长短相差甚大,检测方法不能互相套用,何况要求的准确度又不一。为此,本文就球面曲率半径的各种测量方法、技术和装置,以及它们所能达到的精度等作一甚为详细的描述,以供有关工作人员参考。
Optical instruments, be it photographic systems, microscopy, telescopic systems or multibeam deflecting systems, account for a large proportion of spherical optical components. With the improvement of the instrument performance and the expansion of functions, the accuracy of the surface shape and the radius of curvature of these spherical parts is also increasingly enhanced. Moreover, the curvature radiuses of the spherical parts vary greatly with the different instruments in place, and the detection methods can not be applied to each other , Not to mention the accuracy requirements are different. For this reason, this article gives a very detailed description of various measurement methods, techniques and devices for the radius of curvature of the sphere and the precision they can achieve for the reference of the relevant staff.
