Definition of the noun absorbance
What does absorbance mean as a name of something?
noun - plural: absorbances
- (physics) a measure of the extent to which a substance transmits light or other electromagnetic radiation
Alternative definition of the noun absorbance
- [physics] A logarithmic measure of the amount of light that is absorbed when passing through a substance
Absorbance: In spectroscopy, the absorbance of a material is a logarithmic ratio of the amount of radiation falling upon a material to the amount of radiation transmitted through the material. Absorbance measurements are often carried out in analytical chemistry.
- also known as Optische dichtheid, Absorbans

Absorbance is the reduction in the transmission of light along the light path and may occur due to both dispersion and absorption of light.
by Joseph Sneddon, Terry L. Thiem, Yong-Ill Lee
Absorbance is a unitless number, typically 0.01 to 2.0. 1n practice, it is better to work in the middle of this range (0.1-0.3 is recommended) as the precision is reduced at the extremes due to instrumental noise. Also, the linearity AAS is ...
