absorbance

(A, D, E) optical density; extinction; decadic absorbance. A measure of the amount of light absorbed by a sample. The absorbance (A) equals minus the base-10 log of the transmittance.

absorbance

Absorbance (A) is defined as -log(1-a) = log(1/t), where a is the absorptance and t the transmittance of a medium through which a light beam passes.

Absorbance

In spectroscopy, the absorbance (also called optical density) 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 `...
