Birefringence minerals
WebSome mineral crystals have two different refractive indices and, hence, show birefringence. Examples of minerals that exhibit birefringence are quartz, tourmaline, and calcite. Webdouble refraction, also called birefringence, an optical property in which a single ray of unpolarized light entering an anisotropic medium is split into two rays, each traveling in a …

Webbirefringence: [noun] the refraction of light in an anisotropic material (such as calcite) in two slightly different directions to form two rays. WebIn this case, the mineral will also show birefringence for most orientations, unless one of the privileged directions in the crystal is lined up with the E-W polarizing direction of the …
