absorbances, plural;
  1. 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

  1. optical density: (physics) a measure of the extent to which a substance transmits light or other electromagnetic radiation
  2. In spectroscopy, the absorbance A (also called optical density) is defined as
  3. A logarithmic measure of the amount of light that is absorbed when passing through a substance
  4. The fraction of incident radiation that is absorbed
  5. 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.).
  6. A measure of a material's ability to absorb radiant energy such as light.
  7. Molecules absorb certain energies or wavelengths of light. This property can be exploited for the detection of specific molecules in solution. Spectrophotometers are designed to emit monochromatic (single wavelength) light and to detect the amount of light absorbed by a solution. ...
  8. The ratio of solar radiation versus total radiation absorbed by a glazing system.
  9. The intensity of light at a specified wavelength that has passed through a sample (transmitted light intensity) and I0 is the intensity of the light before it enters the sample or incident light intensity.
