Improved Photometric Standards and Calibration Procedures at NIST
NIST has recently established a detector-based luminous intensity unit (candela, cd), which is derived from the NIST absolute cryogenic radiometer. Subsequently, the luminous flux unit (lumen, lm) and the luminance unit (cd/m(2)) have been established based on the detector-based candela, and now all...
