Extinction coefficient refers to several different measures of the absorption of light in a medium:
- In chemistry, biochemistry, molecular biology, or microbiology, the mass extinction coefficient and the molar extinction coefficient (also called molar absorptivity) are parameters defining how strongly a substance absorbs light at a given wavelength, per mass density or per molar concentration, respectively.
- In physics, the "extinction coefficient" is the imaginary part of the complex index of refraction, which also relates to light absorption.
(For the quantitative relationship between the chemistry and physics definitions, see Mathematical descriptions of opacity.)

- Two-dimensional nanomaterials such as MoS2 are of great interest both because of their novel physical properties and their applications potential. Liquid exfoliation, an important production method, is limited by our inability to quickly and easily measure nanosheet size, thickness or concentration.
