Transmittance

اصطلاح مرجح

1. The transmittance of a sample is the ratio of the intensity of the light that has passed through the sample to the intensity of the light when it entered the sample (T = Iout / Iin ). To convert between the absorbance and transmittance scales, the following equation is used: A = -log T = - log (I / Io). (TIB, BioAssay Ontology). 2. The amount of light the filter transmits at a maximum [units:none] A fraction, as a value from 0.0 to 1.0. (TIB, REPRODUCEME Ontology). 3. Transmittance is defined as the ratio of the transmitted radiant flux to the incident radiant flux in a medium. It is a dimensionless number that, like reflectance, ranges from 0 to 1 for nonfluorescent materials, with the total transmittance being the sum of regular and diffuse transmittance. (ScienceDirect, AI generated definition based on: Experimental Methods in the Physical Sciences, 2014). 4. The transmittance of a material and any surfaces is its effectiveness in transmitting radiant energy; the fraction of the initial (incident) radiation which propagates to a location of interest (often an observation location). This may be described by the transmission coefficient. (Wikipedia)
