National Standard for Luminous Intensity

National Standard for Luminous Intensity (Candela, cd)

This National Standard (NE) realizes the candela (cd), which is one of the seven fundamental SI units. Luminous intensity is a photometric quantity that expresses the transformation between the physical spectral energy intensity of optical radiation and the intensity of the physiological visual perception.

Principle of Realization

• The realization of the candela is based on a technical modeling of the standardized spectral sensitivity of the human eye.
• The process quantifies the conversion between radiant flux and luminous flux, ensuring an accurate representation of light perception.

Calibration and Measurement Capabilities (CMC)

• The number of CMC entries associated with this standard is 5, confirming its international traceability and reliability in metrological applications.

This standard is essential for lighting technology, display calibration, optical metrology, and various industrial applications requiring precise light measurements.
