Abstract:
Theoretically, the photometer spectral mismatch correction factor F is equal to one unit. However, in practice, the photometer is not ideal and the F must be determined. This factor depends from the spectral radiant flux of the source and it needs to be calculated separately for each lamp / photometer, concomitant to the luminous intensity measurements. This paper describes the methodology for the assembly of a spectrocolorimetric system at the Inmetro Photometry system to determine the spectral distribution of lamps to be used in F calculations to determine the luminous intensity. The results obtained and respective validation will be presented.
