Transmittance - Wikipedia
网页In optical physics, transmittance of the surface of a material is its effectiveness in transmitting radiant energy. It is the fraction of incident electromagnetic power that is transmitted through a sample, in contrast to the transmission coefficient , which is the ratio of the transmitted to incident electric field .

Transmittance (Formula & Transmittance to Absorbance …
网页2020年3月30日 · Transmittance Definition: Transmittance is the ratio of light intensity passing through a material to the light intensity hitting the material’s surface. Transmittance Formula: It is calculated by dividing the intensity of the light that passes through the object by the intensity of the incident light.
13.1: Transmittance and Absorbance - Chemistry LibreTexts
网页2022年9月28日 · As light passes through a sample, its power decreases as some of it is absorbed. This attenuation of radiation is described quantitatively by two separate, but related terms: transmittance and absorbance. As shown in Figure 13.1.1a 13.1. 1 a, transmittance is the ratio of the source radiation’s power as it …

Transmittance | Description, Example & Application - Your Physicist
网页2023年3月21日 · Transmittance, also known as transmissivity, is a measure of the ability of a substance to allow light to pass through it. It is the ratio of the amount of light that passes through a sample to the amount of light that falls on it.
Transmittance – transmissivity, diffuse scattering, hemispherical ...
网页The term transmittance is defined as the ratio of transmitted optical power to the incident optical power for some object, for example an optical system. For transmission through flat unstructured surfaces, it is the same as the transmissivity .
Transmittance - an overview | ScienceDirect Topics
网页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.
Transmittance -- from Eric Weisstein's World of Physics
网页Transmittance. The transmittance of an electromagnetic wave incident on a dielectric is defined by. (1) where and are the transmitted and incident electric field. Transmittance of light through an absorbing medium is similarly defined by.
