The second meaning of dichroic refers to the property of a material, in which light in different polarization states traveling through it experiences a different absorption coefficient; this is also known as diattenuation. When the polarization states in question are right and left-handed circular polarization, it is then known as circular dichroism (CD). Most materials exhibiting CD are chiral, although non-chiral materials showing CD have been recently observed. Since the left- and righ… tsem rinpoche passing awayWebJan 1, 2009 · It is well-known that circular dichroism (CD) measurements of anisotropic media may contain artifacts that result from mixed linear anisotropies. Such artifacts are generally considered a nuisance.
