| absorbance | 1. <chemistry, investigation> Absorbance is defined as a logarithmic function of the percent transmission of a wavelength of light through a liquid. 2. <microbiology> This can be used as a measure of the amount of light absorbed by a suspension of bacterial cells or a solution of an organic molecule, it is measured by a colourimeter or spectrophotometer. Absorbance values are used to plot the growth of bacteria in suspension cultures and to gauge the purity and concentration of molecules (such as proteins) in solution. See: absorption.

| absorbance |
Used mostly by chemists, the negative logarithm (base 10) of the transmittance of an absorbing sample, often corrected for reflection by its container. Despite its name, absorbance is a consequence of both scattering and absorption, although scattering is usually assumed to be negligible. To within a constant multiplier, absorbance is absorption optical thickness and depends on the physical thickness of the sample. Compare absorptance.

| absorbance |
The ability of a substance to transform radiant energy into a different form, usually with a resulting rise in temperature. Mathematically, absorbance is the negative logarithm to the base 10 of transmittance.

| absorbance |
Ratio of radiant energy absorbed by a body to the corresponding absorption of a blackbody at the same temperature. Absorbance equals emittance on bodies whose temperature is not changing. (A = 1 - R - T, where R is the reflectance and T is the transmittance.).
