It is the method that the focal of waveguide lens can be measured precisely, its error depends on the precision of readingmicroscope.
对焦点位于波导外部(包括端面)的情况给出了一种精确测量焦距新方法。

In this method, the positioning accuracy and repeated positioning accuracy are tested using the precision linear scale and the readingmicroscope.
该方法利用精密线纹尺和读数显微镜对数控机床的定位精度和重复定位精度进行检验。
