standard illuminants [′stan·dərd i′lü·mə·nəns]

(optics)

Three standard sources of light, designated A, B, and C, used in specifying the light used when colors are matched; A is light from a filament at a color temperature of 2575°C, and B and C, representing noon sunlight and normal daylight respectively, are obtained by modifying A with rigorously specified filters.

No references found			In 1931, The CIE established several standard illuminants for use in color determinations; these illuminants are tables of spectral energy intended to represent "real" light sources. Color control in electrocoat by Lemons, William C. / Coatings World Simulations demonstrate that such a source would be able to approximate the spectral distributions of standard illuminants over the visible range--from 380 nm to 780 nm--with errors on the order of 2 % in luminance and 0. Development of a tunable LED-based colorimetric source by Eppeldauer, George P. / Journal of Research of the National Institute of Standards and Technology The NR3000 Color Difference meter makes all standard color measurements with observation conditions based on CIE standard illuminants (options include C and D65 light sources).
