AbolishedPhotometry - the CIE system of physical photometry
光度学 CIE物理光度系统
Application Summary AI generated
This standard specifies the CIE (International Commission on Illumination) system for physical photometry, defining the spectral luminous efficiency functions and measurement principles for quantifying visible light. It is applied in metrology laboratories and industries for calibrating photometric instruments, such as illuminance meters and luminance meters, and for ensuring consistent light measurement in lighting design, display manufacturing, and optical testing.
