The paper describes the design procedure that allows identification of the optimal parameters of the light source based on optically connected integrating spheres. This source provides a high dynamic range of output radiance with high uniformity of radiance distribution throughout an output aperture. The procedure deals with relative parameters of apertures of primary and secondary integrating spheres, aperture areas, density of lamps and etc. It makes possible calculation of the set of optimal parameters that guarantees the maximal output radiance with high uniformity of its distribution through an output aperture. The paper demonstrates the application of this procedure in the light source design.
