Radiant Intensity

radiant intensity

[′rād·ē·ənt in′ten·səd·ē] (electromagnetism) The energy emitted per unit time per unit solid angle about the direction considered; usually expressed in watts per steradian.

Radiant Intensity

a radiometric unit that characterizes the radiation from a source in a certain direction. Radiant intensity is equal to the ratio of the radiant flux emitted by the source in an infinitesimal solid angle containing the direction considered to the solid angle. The concept of radiant intensity is applicable at distances from the source that greatly exceed the source’s dimensions. The unit of radiant intensity is watts per steradian.
