Abstract.   Numerical modeling of integrating sphere is performed for the case of additional baffle introduced to prevent incidence of direct radiation from emitter positioned near the sphere center upon the measured sample (diffuse reflector). Results of calculation of irradiance distribution inside the sphere under examination are presented.
Keywords: integrating sphere, irradiance, diffuse reflection index, photometric accuracy
