标准和校准实验室最近开发了光谱范围为300 nm至850 nm的封闭式辐照度光源的校准服务。校准基于光纤耦合系统测量的基于源的方法。本文介绍了校准装置、测量模型和相关的不确定度。扩展的测量不确定度估计在测量光谱范围内小于3.3%，可以支持测试和认证行业的需求。

The standards and Calibration Laboratory has recently developed the calibration service for the enclosed-type irradiance light source in the spectral range from 300 nm to 850 nm. The calibration is based on the source-based method measured by a fiber-coupled system. In this paper, the calibration setup, measurement model and the associated uncertainty are presented. The expanded measurement uncertainty is estimated to be less than 3,3 % over the measured spectral range which can support the needs from the testing and certification industry.
