Description

Of the xenon lamp specified by the Japanese Industrial Standard JIS Z-8902 established in 1965, the spectral power distribution had been previously calculated at wavelength intervals of 5 nm by simply averaging the values measured at wavelength intervals of 1 nm in the region including the line spectra and continuous spectrum.<BR>The present paper describes the spectral power distribution of the lamp re-calculated by using weighted mean method, which is a better form for minimizing the error of colorimetric calculation and has been adopted in the new versionof JIS Z-8902-1984.
