| Abstract: | A new shear plate collimation tester on the basis of a single wedge plate using two-time rotatable ways[1] have been developed[2]. It is mainly used to test laser beam collimation, divegrence and amount of defocusing of optical systems in collomator, beam expander and telescope. It can be also used to test wavefront aberrations and laser parameters and to adjust optical systems. In this paper. The basic principles, quantitative interpretation, accuracy analyses, functions and features of the tester are presented. |

| Keywords: | Amount of defocusing Divergence collimation. |
