Uncertainty of near field photometry

Original language description

The paper describes calculation of uncertainty of measurement of luminous intensity distribution of large luminaires at goniophotometer of type 2 with short photometric distance (near field photometry). The short photometric distance causes non-perpendicular incidence of the light coming from the edges of the luminaire onto the photocell of the goniophotometer and thus the measured luminous intensity values could be smaller, than values measured with goniophotometer with adequate photometric distance. The paper should highlight such measurement complication and enlighten operators of goniophotometer of type 2 how to correct measured values of luminous intensity and calculated values of luminous flux of the luminaire.
