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
Focal length is an important optical characteristic parameter of optical lenses and optical instruments. The accuracy of the focal length measurement directly affects the quality of optical instruments and the performance of military optical instruments. Therefore, the accuracy of the measurement of the focal length of the instrument such as focal length meter or optical bench calibration work is a very important issue. At present, the most scientific, economical and effective method is to develop a set of focal length standard lens to calibrate the precision of the instrument for measuring the focal length. This paper introduces the principle of design of focal length standard lens, a high-precision method used to calibrate the standard lens of focal length, and gives the result of final precision calibration of one of the standard focal length lens
