absorptance meaning

• Noun: absorptance  ub'sorptuns
  1. A measure of the rate of decrease in the intensity of electromagnetic radiation (as light) as it passes through a given substance; the fraction of incident radiant energy absorbed per unit mass or thickness of an absorber
     "absorptance equals 1 minus transmittance"
     - absorption coefficient, coefficient of absorption

  Derived forms: absorptances

  Type of: coefficient
