Absorption Factor
(or absorptance), the dimensionless ratio of the radiation flux absorbed by a body to the flux incident on it. In contrast to the absorptivity and absorption coefficient, the absorption factor pertains to radiation of all frequencies and all orientations that is present in the irradiating flux. The factor is dependent on the properties of the body, the state of the body’s surface, the spectral composition of the flux, and the flux’s direction.
