Dichroism - Wikipedia
网页Dichroism. In optics, a dichroic material is either one which causes visible light to be split up into distinct beams of different wavelengths (colours) (not to be confused with dispersion), or one in which light rays having different polarizations are absorbed by different amounts. [1]
Circular dichroism - Wikipedia
网页Circular dichroism (CD) is dichroism involving circularly polarized light, i.e., the differential absorption of left- and right-handed light.
Dichroism Definition & Meaning - Merriam-Webster
网页The meaning of DICHROISM is the property of some crystals and solutions of absorbing one of two plane-polarized components of transmitted light more strongly than the other; also : the property of exhibiting different colors by reflected or transmitted light.
Dichroism – wavelength-dependent transmission, absorption, …
网页The term dichroism can be used for optical elements with a substantial wavelength dependence of the optical properties, or for polarization-dependent absorption.
Physical Principles of Circular Dichroism | Journal of Chemical …
网页2020年11月15日 · Circular dichroism (CD) is the differential absorption of left and right circularly polarized light. It arises from molecular electron oscillations that are driven by both the light’s electric and magnetic fields, where the effects are in phase for one circular polarization and out of phase for the other. We describe these interactions, which ...
What is Dichroism? - GoPhotonics.com
网页2023年4月24日 · Dichroism is an optical property of certain materials to selectively absorb light of different polarizations. This means that the material will appear to have different colors when viewed through polarizing filters oriented in different directions.
Dichroism - an overview | ScienceDirect Topics
网页Dichroism is the phenomenon in which light absorption changes for different directions of polarization. Circular dichroism (CD) refers to the absorption of the two different types of circularly polarized light. 69 Nucleic acids have an intrinsic asymmetry because a chiral sugar is present within the structure.
Dichroism | optics | Britannica
网页form of pleochroism. In pleochroism. …the general term for both dichroism, which is found in uniaxial crystals (crystals with a single optic axis), and trichroism, found in biaxial crystals (two optic axes). It can be observed only in coloured, doubly refracting crystals.
Polarization by Absorption: Dichroism - HyperPhysics
网页A number of crystalline materials absorb more light in one incident plane than another, so that light progressing through the material become more and more polarized as they proceed. This anisotropy in absorption is called dichroism.
Explanation of dichroism from Field Guide to Spectroscopy
网页In spectroscopy, dichroism occurs when a material absorbs left circular polarized light in different amounts than right circular polarized light. This is the basis of dichroism spectroscopy. There are at least three major areas of circular dichroism (CD) spectroscopy: Analysis of chiral molecules.
