Standard Practice for Obtaining Spectroradiometric Data from Radiant Sources for Colorimetry

Importancia y uso:

5.1 The fundamental method for obtaining CIE tristimulus values or other color coordinates for describing the colors of radiant sources is by the use of spectroradiometric measurements. These measurements are used by summation together with numerical values representing the CIE 1931 Standard Observer (CIE Publication 015:2004) and normalized to K_m, the maximum spectral luminous efficacy function, with a value of 683 lm/W.

5.2 This practice provides a procedure for selecting the operating parameters of spectroradiometers used for providing the desired precision spectroradiometric data, for their calibration, and for the physical standards required for calibration.

5.3 Special requirements for characterizing sources of light possessing narrow or discontinuous spectra are presented and discussed. Modifications to the procedures of Practice E308 are given to correct for the unusual nature of narrow or discontinuous sources.
