摘　　要：介绍了透镜中心偏测量仪的校准现状,设计使用光学角规对透镜中心偏测量仪自准直光管的示值误差进行校准。通过分析光学角规的基本原理,偏向角的定义,偏向角和楔角的转换关系,详细说明如何选择光学角规以及如何使用光学角规实现透镜中心偏测量仪自准直光管示值误差的校准与溯源。选用标称值分别为2′与5′,并经过国家计量院溯源的一等光学角规,对1台单光路设备和1台双光路设备进行校准,测量重复性均优于0.1″,不确定度达到0.11″。结果表明,光学角规可以有效解决高精度透镜中心偏测量仪自准直光管示值误差的校准溯源问题。The current calibration status of the lens center deviation measuring instrument was introduced,and the optical angle gauge was designed and used to calibrate the indication errors of the auto-collimated light tube of lens center deviation measuring instrument.By analyzing the basic principles of optical angle gauges,the definition of deviation angle,and the conversion relationship between deviation angle and wedge angle,a detailed explanation of how to select and use an optical angle gauge to calibrate and trace the indication errors of the auto-collimated light tube of lens center deviation measuring instrument was provided.The first-class optical angle gauges with nominal values of 2'and 5'and traced by the National Institute of Metrology were selected to calibrate a single optical path device and a dual optical path device.The measurement repeatability is better than 0.1",and the uncertainty reaches 0.11".The results show that the optical angle gauge can effectively solve the calibration and traceability problems of the auto-collimated light tube indication errors of high-precision lens center deviation measuring instruments.
