四面体棱镜是分步重复照像机中的主要光学元件,精度要求高,加工难度大。面临这些困难,我们组织了老工人,认真学习了毛主席关于:“社会的财富是工人、农民和劳动知识分子自己创造的。只要这些人掌握了自己的命运,又有一条马克思列宁主义的路线,不是回避问题,而是用积极的态度去解决问题,任何人间的困难总是可以解决的”教导。进行了社会调查;仔细分析了这种四面体棱镜的特点及关键所在。其特点是四面体棱镜自身具有三个全反射面,能使出射光线经过反射后严格平行于入射光线。对于棱镜本身来讲,要求材料质量好,反射面的平面性高,最重要的是要求每个直角误差很小。根据这些特点,首先确定用什么方法加工,更重要的是把关键放在解决角度的精密测量问题上。经过反复实践和科学分析,最后经过不到一年的时间,终于试制成功。根据分步相机产品要求,现已投入批量生产。给毛主席无产阶级教育路线争了光,给社会主义祖国争了光。
Tetrahedral prisms are the main optical components in the step-and-repeat camera, which require high precision and difficult processing. Faced with these difficulties, we organized veteran workers and earnestly studied Chairman Mao’s statement: “The wealth of society is created by the workers, peasants and labor intellectuals themselves. As long as these people grasp their own destiny, they have a Marxist-Leninist line Instead of avoiding the problem, we should adopt a positive attitude to solve the problem. Any human problem can always be solved. ” Conducted a social survey; careful analysis of the characteristics of such tetrahedral prism and the key. Its characteristic is the tetrahedral prism itself has three total reflection surface, can make the outgoing light after reflection strictly parallel to the incident light. For the prisms themselves, require good material quality, high flatness of the reflective surface, the most important is the requirement that each right-angle error is small. According to these characteristics, it is first determined what method of processing, more importantly, the key to solve the problem of precision measurement point of view. After repeated practice and scientific analysis, finally after less than a year’s time, finally trial success. According to step-by-step camera product requirements, is now put into mass production. Win the favor of Chairman Mao’s proletarian education program and win the war for the socialist motherland.
