Term: spectral transmissivity, <of an absorbing material>
Synonym1:
Synonym2:
Synonym3:
Symbol: τi,o(λ)
Definition: spectral internal transmittance of a layer of an absorbing material such that the path of the radiation is of dimension length, and under conditions in which the boundary of the material has no influence

Note 1 to entry: The unit of length has to be specified. If a new unit of length is used that is k times the magnitude of the original one, then the value of τi,o(λ) will change to τ i,o (λ)= [ τ i,o (λ)] k MathType@MTEF@5@5@+= feaagKart1ev2aaatCvAUfeBSjuyZL2yd9gzLbvyNv2CaerbbjxAHX garuavP1wzZbItLDhis9wBH5garmWu51MyVXgaruWqVvNCPvMCG4uz 3bqee0evGueE0jxyaibaieYdi9WrpeeC0lXdh9vqqj=hEeea0xXdbb a9frFj0=OqFfea0dXdd9vqaq=JfrVkFHe9pgea0dXdar=Jb9hs0dXd bPYxe9vr0=vr0=vqpWqaaeaaciWacmGadaGadeaaeaGaauaaaOqaai qbes8a0zaafaWaa0baaSqaaiaabMgacaqGSaGaae4BaaqcbaCaaaaa kiaacIcacqaH7oaBcaGGPaGaeyypa0Jaai4waiabes8a0naaBaaale aacaqGPbGaaeilaiaab+gaaeqaaOGaaiikaiabeU7aSjaacMcacaGG DbWaaWbaaSqabeaacaWGRbaaaaaa@4AFD@ .
