Transmittance - Meaning, Definition & English Examples

Transmittance is the measure of how much light or other radiation passes through a material, expressed as the ratio of transmitted to incident energy. It is commonly used in optics and spectroscopy.

transmittance

/trænzˈmɪtəns/ /trænzˈmɪtəns/

Definition:

The fraction of incident light or energy that passes through a medium.

Synonyms:

transmission, permeability, conductance, passage

Part of Speech:

noun

Antonyms:

opacity, blockage, absorption

Common Collocations:

high transmittance, low transmittance, light transmittance, thermal transmittance

Derivatives:

transmit, transmitter, transmissible

Usage Tips:

Use "transmittance" when discussing light or energy passing through materials like glass or air.

Common Phrases:

"transmittance spectrum, " "optical transmittance, " "UV transmittance"

Etymology:

Derived from Latin "transmittere," meaning "to send across."

Examples:

  • 1. The glass has high transmittance for visible light.
  • 2. Scientists measured the transmittance of the new solar panel coating.
  • 3. Low transmittance in this filter blocks harmful UV rays.
  • 4. The material's thermal transmittance affects its insulation properties.
