Definition of absorbance in English:
absorbance
noun əbˈsɔːb(ə)nsəbˈzɔːb(ə)ns-ˈsôr-
Physics A measure of the capacity of a substance to absorb light of a specified wavelength. It is equal to the logarithm of the reciprocal of the transmittance.
a plot of absorbance versus wavelength would give a Gaussian curve
count noun absorbances were recorded with a clinical photometer
Example sentencesExamples
- Then, absorbances at the four wavelengths were calculated.
- The isotropic emission spectra were normalized to the corresponding absorbance at the excitation wavelength.
- In these experiments electron absorbances were measured as a function of increasing laser intensity and, subsequently, as a function of decreasing laser intensity.
- The absorbance measured is directly proportional to the concentration of human leptin present.
- The total cavity loss is then the sum of the mirror transmission and the sample absorbance.
