divergent lens system

基本解释

The optical system consists of glass reflector and divergent lens.
系统包括用玻璃精制而成的反光镜和发散透镜。
Based on the divergent beam system of lens, the fully-leaky guided mode characterization of liquid crystal layer have been studied by means of the prism-coupling technique.
基于透镜扩束系统，应用棱镜耦合技术对液晶层的全漏导模特性进行了研究。
While a laser beam goes through a cylindrical lens, the divergent angle width can be precisely determined with a high resolution CCD and a data microcomputer processing system.
该方法的基本原理是利用准直激光束通过柱面镜产生扇形折射光束，折射光束散开的宽度同柱面镜曲率半径直接相关。
