Visible Radiance

Other Names



Visible Radiance is the intensity of visible radiation. In radiometry, a measure of the intrinsic radiant intensity emitted by a radiator in a given direction. Radiance is measured in watts per square meter per steradian.
Visible Radiation refers to electromagnetic radiation capable of evoking the sensation of vision in a normal human observer. The indefinite range of wavelengths of visible radiation is between 400 and 700 nm. Radiance is a radiometric term for the rate at which radiant energy in a set of directions confined to a unit solid angle around a particular direction is transferred across unit area of a surface (real or imaginary) projected onto this direction.
