ROLE OF ERROR IN SPECTRAL MEASUREMENTS IN THE PHOTOMETRY OF THERMAL AND QUASIMONOCHROMATIC RADIATION

摘要

A metrological analysis of the influence of errors in spectral measurements on the error of light calibrations of thermal and quasimonochromatic radiation sources and photometers is presented. It is shown that quasi- monochromatic light-emitting diodes, rather than thermal filament lamps, should be used as primary sources in order to maintain low errors in the measurement of the luminous quantities of quasimonochromatic radiation.
