Due to the wide spectrum range and the good performance of exit surface uniformity and angle uniformity, integrating sphere is close to the ideal Lambert uniform light source. In this paper, the principle of large dynamic range radiation standard transmission based on integrating sphere light source was proposed. That is to say, under the premise of equal color temperature adjustment, a monitoring radiometer based on a linear silicon detector with a large dynamic range response, and an adjustable aperture can transfer the spectral radiance working standards of the irradiance standard lamp-solar diffuser system to a large dynamic range adjustable integral sphere light source. Thus, the dynamic range of radiation standards can be expanded. Herein, we prepared a large dynamic adjustable aperture and further discussed the spectral matching and the impact of silicon detector nonlinearity on the accuracy of radiation standard transmission. Finally, in spectrum range of 400~2 500 nm, the uncertainty of 6 orders of magnitude radiation standard is 4.3%~6.1% in integrating sphere source. It is of great significance to the quantitative development of radiometric.
