Question

What is the difference between absorbance and optical density?

Answer 1

HEY!

HERE IS THE ANSWER TO YOUR QUESTION:

Optical density is the degree to which a refractive medium retards transmitted rays of light.

Absorbance is a measure of the capacity of a substance to absorb light of a specified wavelength.

The optical density measurement takes both, the absorption and scattering of light, into consideration.

The absorbance measurement takes only the absorption of light into consideration.
