Absorption coefficient
The absorption coefficient measures how rapidly light intensity decreases as it travels through a material, typically as an exponential decay per unit distance.

OpacityRelated: It quantifies the absorptive contribution to opacity along a radiation path.
Spectral radianceRelated: Absorption reduces spectral radiance along a path through a medium.
DichroismRelated: Dichroism is a difference in absorption coefficients for different polarizations.
Diffuse reflectanceRelated: Absorption removes photons that might otherwise return from the sample.
Kubelka–Munk equationRelated: It supplies the K term governing light loss inside the layer.
