Definition of transmittance in English:
transmittance
nountransˈmɪt(ə)nstrɑːnzˈmɪt(ə)nstranzˈmɪt(ə)nstrɑːnsˈmɪt(ə)ns
Physics The ratio of the light energy falling on a body to that transmitted through it.
Example sentencesExamples
- The apparatus determines the transmittance of light through the sample leaf at two wavelengths.
- A series of spectral data acquired were first background subtracted, and then corrected for emission filter transmittances.
- Standard curves established for each stock suspension showed that light transmittance at the characteristic wavelength was inversely proportional to the concentration of gold colloid.
- Designed for spectral analysis of microscopic samples as small as 1 mm, the instrument can measure by transmittance, absorbance, reflectance, fluorescence, and polarization.
- 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.
