absorptivity

(ˌæbsɔːpˈtɪvɪtɪ; -zɔːp-)
n
(General Physics) physics a measure of the ability of a material to absorb radiation, equal to the internal absorptance of a homogeneous layer of the material under conditions in which the path of the radiation has unit length and the boundaries of the layer have no influence

Beer-Lambert Law. If the scattering effects of the measured cells are negligible, the decreased light intensity is only caused by the absorption of chemical composition of cells.
It is important to note that the linearity of Beer-Lambert Law is limited by chemical and instrumental factors such as deviations in absorptivity coefficients at high concentrations, scattering of light due to particulates in the sample, fluorescence sample, changes in refractive index at high analyte concentration, shifts in chemical equilibria as a function of concentration, stray light, and nonmonochromatic radiation.
The tester adopts the ultraviolet ray absorption principle and is based on the Beer-Lambert law to inspect the ozone concentration without the use of chemicals.
