BackForward Variable: Background Luminance (surface)

Full name Background Luminance (surface)
Definition Luminous flux received from the background, per unit solid angle and per unit area where the Luminous flux is a quantity derived from radiant flux by evaluating the radiation according to its action upon the International Commission on Illumination standard photometric observer. (symbol: L; unit: lm. m–2. sr–1 = cd . m–2 )
Measuring Units cd . m –2 Uncertainty Units %
Horizontal Res Units Vertical Res Units
Stability Units % (Stability /decade)
