Key Concepts

Photometry

Photometry is the science of measuring visible light in terms of its brightness as perceived by the human eye. It entails quantifying light based on how humans perceive various wavelengths, focusing on aspects like luminous intensity and luminous flux rather than total radiant energy.

Photometric Units

Photometric measurements are expressed using units such as candela (a measure of luminous intensity), lumen (a measure of luminous flux), and lux (a measure of illuminance). These units incorporate the human eye’s varying sensitivity to different wavelengths, ensuring that the measured values correspond to perceived brightness.
