ab·sorb·ance
ab·sorb·ance/əbˈzôrb(ə)ns/
noun
a measure of the capacity of a substance to absorb light of a specified wavelength. It is equal to the logarithm of the reciprocal of the transmittance.
"a plot of absorbance versus wavelength would give a Gaussian curve"
Absorbance is defined as "the logarithm of the ratio of incident to transmitted radiant power through a sample (excluding the effects on cell walls)".
