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.

无焦非球面系统是激光发射系统采用的主要结构之一。

The unfocused aspherical surface system is one of the main structure of large emiting system.
