在使用JSG-1型表面光洁度显微镜时,经常会碰到光带和被测件表面像不能在视场中央重合的现象。从原理上说,解决这个问题并不困难,因为引起光带、工件像位置偏离的原因主要是两个物镜的轴向位移。但由于仪器结构的特殊性,实际的调整还是比较费时的。为便于仪器操作者调整,在这里介绍一种比较简便的方法,供参考。 In the use of JSG-1 surface finish microscope, often encounter light and the surface of the device under test can not coincide in the field of view coincidence phenomenon. In principle, to solve this problem is not difficult, because the cause of the band, the workpiece image position deviation is mainly the axial displacement of the two objectives. However, due to the special structure of the instrument, the actual adjustment is rather time-consuming. In order to facilitate the adjustment of the instrument operator, here is a relatively simple method for reference.
