Leuchtdichten
Leuchtdichte, in English luminance, is the photometric quantity that describes how bright a surface appears to the human eye when viewed from a given direction. It represents the luminous intensity per unit area emitted, reflected, or transmitted by the surface into a specified solid angle. The SI unit is candela per square meter (cd/m^2); the unit is also commonly called a nit, where 1 nit equals 1 cd/m^2.
Luminance is a directional quantity and is related to the spectral power distribution of the light and
Measurement of luminance is performed with luminance meters or calibrated cameras that detect light in a defined
Applications and relevance: Luminance is central in display technology to specify screen brightness, in signage and
