Dichroism wikipedia
Circular dichroism (CD) is dichroism involving circularly polarized light, i.e., the differential absorption of left- and right-handed light. Left-hand circular (LHC) and right-hand circular (RHC) polarized light represent two possible spin angular momentum states for a photon, and so circular dichroism is also referred to as dichroism for spin angular momentum. This phenomenon was discovered by Jean-Baptiste Biot, Augustin Fresnel, and Aimé Cotton in the first half of the 19th century. Circula… WebThe term dichroism (with the corresponding adjective dichroic) is used with two different meanings, explained in the following sections. Wavelength-dependent Transmission The term can be used for optical elements which somehow act on light with a substantial dependence on the optical wavelength .
