- See birefringence.
- the refraction of light in 2 directions, which creates two distinct pictures. The effectiveness of double refraction is possessed by all crystals except those of isometric system. A uniaxial crystal is considered optically good (love quartz), or optically unfavorable (like calcite), or even have good, or bad, double refraction, in accordance once the optic axis may be the axis of minimum or biggest elasticity for light; a biaxial crystal is similarly designated if the same relation holds when it comes to severe bisectrix.
- splitting a ray into two synchronous rays polarized perpendicularly
