焦距标准透镜的焦距精度标定的研究

焦距是光学透镜和光学仪器的重要光学特性参数。焦距值测量的准确性直接影响光学仪器的质量和军用光学仪器的性能发挥。因此，对测量焦距的仪器如焦距仪或光具座的精度标定工作就是极重要的问题。当前，最科学、最经济、最行之有效的方法就是研制出一套焦距标准透镜，对测量焦距的仪器进行精度标定。本文介绍了焦距标准透镜设计原则，标定焦距标准透镜所采用的一种高精度方法，并例举了其中一对焦距标准透镜最后精度标定的结果

Research on the Focal Standard Lenses Used for the Measuring Appliance of Focal Length

Focal length is one of the most important optical characteristic parameter of optical lenses and optical instruments. The measuring accuracy of the focal length has direct influence on the quality of optical instruments and the performance of military optical instruments. Therefore, it is very critical that the accuracy of the appliances for measuring focal length, such as optical benches and testing focal length equipment, is calibrated. In the state of art, it is one of the most scientific and economical methods to derelope a series of standard focal lenses and calibrate the appliances for measuring focal length with them.The design principle of the standard lenses and the new precise methods for calibrasting the standard lenses are presented in the this paper. The calibrating results of the standard lenses are also included.
