WebThe modified Stefan-Boltzmann law for a non-blackbody is given by: Q radiation = ε σ A ( T s4 - T a4 ) where e is the emissivity of the radiating surface defined as the ratio of the emissive power of the surface to the emissive power of a blackbody at the same temperature. Materials are assigned an emissivity value between 0 and 1.0. Webrepresentative, the orthogonal projection of either the boundary of the illuminating surface projected on the exterior surface of the lens (a-b), or the light-emitting surface (c-d), in a plane perpendicular to the direction of observation and tangential to the most exterior point of the lens. As shown in the figure below.
