Measurement of Spectral Irradiance
光谱辐射照度测试研究

Measurement method for spectral irradiance using high temperature black body was describe,which realizing spectral irradiance with low uncertainty.The measurement results were given and it could be transferred to spectral irradiance standard lamp using comparison method.And,the black body BB3200k and spectral irradiance measurement facility were presented.The obtained results show that spectral irradiance unit can be realized with high stability and low uncertainties based on high temperature black body.
