摘　　要：基于高温黑体辐射源和双光栅光谱辐射比较测量系统,中国计量科学研究院自主研制了新一代光谱辐射照度国家基准装置,波长范围覆盖230~2550 nm,以一组稳定的卤钨灯作为副基准灯组,保存和传递光谱辐射照度量值。黑体的温度溯源至铂-碳Pt-C和铼-碳Re-C共晶点黑体,在3021 K采用钨碳-碳WC-C共晶点黑体进行验证。采用新基准装置,2017年-2019年NIM参加国际计量局组织的光谱辐射照度国际关键比对CCPR-K1.a,比对由全俄光学物理学测量研究院(VNIIOFI)主导,共有12个实验室参加。比对结果表明:除少数实验室外,在250~290、300~1300、1500~2500 nm波长范围,各参比实验室之间的一致性分别为±2.0%、±1.0%和±2.0%。在紫外、可见和近红外波段,NIM与国际比对参考值的平均相对偏差分别为0.13%、0.28%和0.15%。在250~2500 nm全波段,NIM与国际比对参考值的平均相对偏差为0.17%,与2004年平均相对偏差0.9%相比,测量能力提升显著。Based on a high-temperature blackbody and a double grating spectral comparison measurement system,the new primary standard apparatus of spectral irradiance was developed at the National Institute of Metrology(NIM)in the spectral wavelength from 230 to 2550 nm.Stable 1000 W tungsten halogen lamps are the secondary primary standard for spectral irradiance values.The temperature measurement of the high-temperature blackbodies was traced to the Pt-C and Re-C fixed-point blackbodies and checked against the WC-C fixed-point blackbody at 3021 K.From 2017 to 2019,NIM participated in the new international comparison of spectral irradiance CCPR-K1 using the newly developed primary standard apparatus.An organized by BIPM.The comparison was piloted by VNIIOFI from Russia,with 12 laboratories participating.The comparison results show that,except for a few laboratories,the consistency of the participated laboratories is±2.0%,±1.0%,and±2.0%at wavelengths of 250 to 290 nm,300 to 1300 nm,and 1500 to 2500 nm.The average relative deviation between NIM and the KCRV(key comparison reference values)is 0.13%,0.28%and 0.15%,respectively,in the ultraviolet,visible,and near-infrared wavelengths.The whole wavelength from 250 to 2500 nm,the average relative deviation between NIM and the KCRV is 0.17%.Compared with the average relative deviation of 0.9%in 2004,the measurement capability of spectral irradiancehas significantly improved.
