Dichroic absorption
Did you know?
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… WebMar 19, 1998 · The ternary blend has high absorption dichroic ratios DR A (ratio between absorption for p- and s-polarized light) of up to 13 at 440 nm, resulting from a high degree of orientation of EHO-OPPE.
