dichroism
Americannoun
-
Crystallography. pleochroism of a uniaxial crystal such that it exhibits two different colors when viewed from two different directions under transmitted light.
-
Chemistry. the exhibition of essentially different colors by certain solutions in different degrees of dilution or concentration.
noun
-
Also called: dichromaticism. a property of a uniaxial crystal, such as tourmaline, of showing a perceptible difference in colour when viewed along two different axes in transmitted white light See also pleochroism
-
a property of certain solutions as a result of which the wavelength (colour) of the light transmitted depends on the concentration of the solution and the length of the path of the light within the solution

Researchers at the University of Ottawa have found that using helical light beams in disordered solids reveals a phenomenon known as dichroism, which is differential absorption of light.
From Science Daily ● Feb. 29, 2024
The study, titled "Intrinsic dichroism in amorphous and crystalline solids with helical light," was published in Nature Communications.

However, a new uOttawa study disproves this theory and shows that amorphous solids actually exhibit dichroism, meaning that they selectively absorb light of different polarizations.
From Science Daily ● Feb. 29, 2024
"Our team developed a new method to show that non-crystalline solids can exhibit helical dichroism, which means they react differently to light that twists in different directions," says Professor Bhardwaj.

Slates, shales and clays yield biotite hornfelses in which the most conspicuous mineral is black mica, in small scales which under the microscope are transparent and have a dark reddish-brown colour and strong dichroism.
