【 摘 要 】
This paper presents a comparative study of the relative spectral radiance measurements of incandescent and LED light sources performed in two different setups with a rotating-mirror-goniophotometer. In one configuration the light is reflected by the goniophotometer mirror, while in the other the mirror is not used. This study permits to determine a spectral correction factor at each measured wavelength in order to obtain a more precise value for the Correlated Color Temperature (CCT)
