WebBiaxial crystals have three different crystallographic axes. They also have two unique directions within the crystal that resemble the unique optic axis in a uniaxial crystal. The Greek letters α (alpha), β (beta), and γ … 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 thu…
