Abstract
The paper presents the mathematical technique for calculation of the output radiance of the precise uniform light sources which have a form of several or multiple optically connected integrating spheres. The light source contains several primary integrating spheres of small diameters which are installed on a secondary integrating sphere of bigger diameter. The proposed technique takes into account the fluxes multiple times coming from the secondary integrating sphere to the primary ones and in opposite direction. The proposed light sources can be considered as one of the best candidates for calibration of high level optical instruments working in optical range 0.4 - 2.2 mkm including radiometers for remote sensing.
