该方法借助一个焦距较长的凸透镜与被测凹透镜组成无焦系统，可以使准直管出射光束的张角发生改变；
Firstly, a telescope system is made up with a concave lens and a long-focus convex lens, by which the angle of the parallel beam from the collimator can be change.
用一辅助凸透镜与一测微目镜进行平行光束的会聚，测出准直管玻罗板线对在辅助凸透镜焦平面上所成像的大小；
Then using another convex lens and a micrometer eyepiece the altered parallel rays is focused, and the imaging size of line pair of collimator imaged on the another convex lens is measured.
