The direction between the optic axes in a biaxial crystal.
The range in a doubly refracting crystal in direction of which no dual refraction happens. Crystals belonging to the tetragonal and hexagonal systems have one optic axis, coincident with their straight crystallographical axis: therefore they have been said to be uniaxial. Crystals belonging to the orthorhombic, monoclinic, and triclinic systems have actually two optic axes, and therefore are biaxial.
Synonyms Optic, Optical. The previous is chiefly stated associated with anatomy of this eye as well as the physiology of vision, the latter chiefly associated with the science of optics: as, optic nerve, system, lobe; optical perspective, center, result.
