ab•sorb•ance*æbˈsɔr bəns, -ˈzɔr-(n.)
the capacity of a substance to absorb radiation.
Origin of absorbance:
A logarithmic measure of the amount of light that is absorbed when passing through a substance.
In spectroscopy, the absorbance of a material is a logarithmic ratio of the radiation falling upon a material, to the radiation transmitted through a material. Absorbance measurements are often carried out in analytical chemistry. In physics, the term spectral absorbance is used interchangeably with spectral absorptance or absorptivity. In this case it has a slightly different meaning: the fraction of radiation absorbed at a specific wavelengths.
