Using polarized light means substantial reduction in light intensity. Theferore polarized light is used only if non-isotropic phenomena are expected (e.g. orientation in crystalline or in polymeric materials), in the case of kiroptic spectroscopy (ORD and CD = optical rotation dispersion and cricular dichroism) and in scattering phenomena, where the degree of depolarization provides additional information of the moblity of molecules.

Dear Prof. Gyorgy:

Many thanks.

Jean Rene Grezes

Please search in R.G. prior you post a question about unpolarized light! Why:

Alok Ranjan Tiwary posted a quite similar question on RG four years ago.(2013)

How do you define unpolarized light? What is the difference between polarized light and unpolarized light?

Read please all the answers posted at this time.
