光谱辐射亮度和光谱辐射照度国家基准装置始建于1975年,是光学领域的重要基准量值。其中,光谱辐射照度被国际计量局(BIPM)确定为光度辐射度(CCPR)国际关键性量值比对项目的第一项,定期举办国际关键性量值比对,确保量值的国际等效一致。1989年、2000年分别对基准装置进行第一次和第二次
Spectral radiation brightness and spectral irradiance National benchmark device was founded in 1975, is an important reference value in the field of optics. Among them, the spectral irradiance was identified by the International Bureau of Weights and Measures (BIPM) as the first item in the international key quantitative comparison of photometric irradiance (CCPR), and international periodic key-value comparison was held periodically to ensure the international equivalence of the value Consistent. In 1989 and 2000, the first and second baseline installations were carried out respectively
