Web∞) is referred to as the Kubelka-Munk function, where R ∞ is the absolute reflectance of the sample, K is the absorption coefficient, and S is the scattering coefficient. The scattering coefficient varies depending on the size and density of the particles. For actual measurements, the absolute reflectance is difficult to determine. WebThe theory works best for optically thick materials where > 50 % of light is reflected and < 20 % is transmitted. Kubelka and Munk Zeit. Für Tekn. Physik, 12, p593 (1931).
