the splitting of a ray of light into two parallel rays of perpendicular polarization by passage through an optically anisotropic medium
is a property of light that is created by an anisotropic structure in which the optical properties are different for each polarization A wire-grid polarizer is a good example of a birefringent structure in which the optical properties in the two polarizations are very different, one direction being metallic and the other direction dielectric in nature Birefringence is typically used to create waveplates or similar devices
The numerical difference between the highest and lowest refractive index of a mineral Minerals with birefringence exhibit interference colors in thin section when viewed with crossed-polarized light
The numerical difference in refractive indices for a substance In a given crystal view, the interference color (retardation) between crossed polars depends on the birefringence and thickness: Retardation (nm) = 1000 x thickness (m) x birefringence
Optically anisotropic substances are double-refracting In birefringent crystals, light is resolved into two components that are polarized at right angles to each other and that travel at different velocities through the substance Thus, the crystal exhibits two refractive indicies (one for each ray) This phenomenon is called birefringence Numerically, it is the difference in index between the grater and lesser index values of any anisotropic material
Birefringence is another name for double refraction In doubly-refractive stones, the light entering the stone is split into two light rays, and the rays travel in different paths These stones have more than one refractive index Calcite, peridot, zircon, tourmaline, and titanite are doubly-refractive stones
{i} (in Optics) breakage of a light ray into two different directions therefore creating two separate light rays (occurs in many types of crystals - also known as double refraction)
when a single incident beam is split into two refracted beams Both of the refracted beams are parallel, with one offset from the other
The appearance under the microscope of congo red staining of amyloid
A material is birefringent if the index of refraction differs for incident electromagnetic waves with different polarizations Examples of birefringent media include calcite (CaCO3), quartz (SiO2), and ice (H2O)
The appearence under the microscope of congo red staining of amyloid
Optical distortion caused by different indices of refraction for separate directions of polarization, often caused by stress in the optical medium Produced during CD or DVD injection molding by shrinkage, flow lines, and inclusions in the substrate Usually more severe near the outer diameter
(복굴절)
splitting a ray into two parallel rays polarized perpendicularly
(general optics) aka: 'double refraction' The velocity of a wave propagating through anisotropic matter depends on the orientation of the electric field vector relative to the optical axes of the matter This effect is called birefringence If the wave is arbitrarily polarized, it splits into components with different propagation constants Depending on its direction, it may also split into an ordinary (o) wave and an extraordinary (e) wave When these partial waves are recombined, their relative phase is different from its initial value, so the state of polarization has effectively varied
