摘　　要：分析了接触式亮度计的结构、测量原理和应用特点，同时设计了一种适于接触式亮度计校准的均匀漫射面源，以此校准3台接触式亮度计并与中国计量科学研究院的接触式亮度计检定标准进行比对，结果表明该校准方法溯源准确，结果有效、可行。最后对几种常用漫射面源应用于接触式亮度计校准的可行性进行了简要讨论。The structure, measuring principle and applying properties of a contact-type luminance meter are described. And a light source which can provide a uniform diffuse surface is presented and applied to calibrate three contact-type luminance meters. In comparison with the luminance standard in National Institute of Metrology for verifying contact-type luminance meters, this calibrating method shows good traceability and accurate certified value. Finally, the practicality of applying several commonly diffuse surfaces to calibrate contact-type luminance meters is discussed briefly.
