Definitions

CIE Standard Illuminants

Illuminants A and D65 defined by the CIE in terms of relative spectral power distributions [1].

Note 1: These illuminants are intended to represent:
  • A: Planckian radiation at a temperature of about 2,856 K

  • D65: The relative spectral power distribution representing a phase of daylight with a correlated color temperature of approximately 6,500 K (called also “nominal correlated color temperature of the daylight illuminant”)

Note 2: Illuminants B and C and other D illuminants, previously denoted as “standard illuminants,” should now be termed “CIE illuminants.”

CIE Standard Sources

Artificial sources specified by the CIE whose radiation approximate CIE standard illuminants.

Note: CIE sources are artificial sources that represent CIE illuminants.

Overview

As shown already in the section Definitions, one has to distinguish between illuminants and sources: The term...
