Web2.3.1 Beer–Lambert Law. The absorption coefficient describes the intensity attenuation of the light passing through a material. It can be understood as the sum of the absorption cross-sections per unit volume of a material for an optical process [7]. The higher , the shorter length the light can penetrate into a material before it is absorbed.
