【摘要】 分析了激光测量光路的特点和装校要求,给出了采用可见光源、分划板装校激光光路的原理。以预放测量模块为例,介绍了装校的流程及装校中的注意事项,分析了装校所能达到的精度,并用内调焦望远镜进行了装校精度检查。结果表明,采用可见光源、分划板装校的激光光路透镜光轴正过心的偏心极限误差小于等于0.07 mm,光轴倾斜极限误差小于等于25″。更多还原

【Abstract】 The character and alignment demand of laser optical path were analyzed,and a method of fast adjustment and alignment of optical path by using visible light source and glass grid was given.The adjustment process and the problem in operating wereexampled by Pre-amplifier diagnostic module of prototype facility,and the adjustment and alignment error was calculated and checked by using a collimeter.Result shows the lens axle alignment error is less than 0.07 mm in radius and less than 25″ in direction.更多还原
