Discover the world's research. 20+ million members; An optic axis of a crystal is a direction in which a ray of transmitted light suffers no birefringence (double refraction). An optic axis is a direction rather than a single line: all rays that are parallel to that direction exhibit the same lack of birefringence. Crystals may have a single optic axis, in which case they are uniaxial, or two different optic axes, in which case they are biaxial. Non-crystalline materials generally have no birefringence and thus…

WebNewport provides a wide range of photonics technology and products designed to enhance the capabilities and productivity of our customers’ applications. WebFor biaxial crystals, there are two "optic axes." For uniaxial crystals, which are used in the construction waveplates, there is one optic axis direction and it is parallel to the extraordinary index of refraction (ne). Therefore, to change polarized light, the "optic axis" of a waveplate is perpendicular to the "optical axis" of the lens system.
