Transmittance Definition from Science & Technology Dictionaries & Glossaries

Energy Glossary
TRANSMITTANCE
The time rate of heat flow per unit area under steady conditions from the air (or other fluid) on the warm side of a barrier to the air (or fluid) on the cool side, per unit temperature difference between the two sides.

Telecommunication Standard Terms
transmittance
The ratio of the transmitted power to the incident power. (188 ) Note 1: In optics, transmittance is usually expressed as optical density or in percent. Note 2: Transmittance was formerly called "transmission."

General Chemistry Glossary
transmittance (percent transmittance; transmission)
(T) Compare with absorbance .The transmittance is the fraction of radiant intensity transmitted by a sample,T = I/I0 where T is the transmittance and I, I0 are the radiant intensity of the radiation after and before passing through the sample. The percent transmittance is the transmittance times 100%.
