Transmittance

Scopri la traduzione in italiano del termine transmittance nel Dizionario di Inglese di Corriere. 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. The range of transmittance of glasses (except for metallic glasses) is generally limited in the optical range by intrinsic mechanisms, i. When two different samples must be compare they must be prepared the same way. Transmittance definition is - transmission.

When a numerical standard is used for the reference material, it is especially important to find out how the original physical standard was prepared so that the sample being measured can be prepared the same way. The absorbance and transmittance are related to each other. But, after the use of microprocessors, it automatically converts transmittance into absorbance. The use of absorbance and transmittance is a personal preference. Use this chart as a handy reference in the lab, classroom or field.

Inter-relation: When all the light hitting the surface of the object is absorbed then the transmittance is and the absorption is 1. The transmittance is also often reported as internal transmission and defined as: External transmittance includes both the absorption loss of the material and the loss of light due to reflection at the two glass surfaces, while the internal transmittance only includes absorption losses of the material. 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.

To compute the transmittance , the direct incident radiation has to be measured in a fixed position, which can be done in a small canopy gap because of the reduced viewing angle of the sensor.

Synonyms for transmittance in Free Thesaurus. Antonyms for transmittance. UV transmittance , or total solar energy transmittance. Main Difference – Absorbance vs. Absorbance and transmittance are two relate but different quantities used in spectrometry.

The main difference between absorbance and transmittance is that absorbance measures how much of an incident light is absorbed when it travels in a material while transmittance measures how much of the light is transmitted. Par exemple on peut calculer la transmittance de la créatinine du rein. Absorbance definition, the capacity of a substance to absorb radiation, expressed as the common logarithm of the reciprocal of the transmittance of the substance. In termotecnica la trasmittanza termica (indicata con U) è una grandezza fisica che misura la quantità di potenza termica scambiata da un materiale o un corpo per unità di superficie e unità di differenza di temperatura.

With this type of measurement, light attenuation indicates the concentration of dust inside the duct. These measuring devices are specially designed for medium to high dust concentrations and large duct diameters. Transparent wood (TW) is an emerging optical material combining high optical transmittance and haze for structural applications. Unlike nonscattering absorbing media, the thickness dependence of light transmittance for TW is complicated because optical losses are also related to increased photon path length from multiple scattering.

In the present study, starting from photon diffusion equation.
