    The direction in a doubly refracting crystal along which light travels without undergoing double refraction.

    • In calcite, the optic axis is aligned with the crystal's symmetry.
    • Light passing along the optic axis behaves as if the crystal were isotropic.
    • The orientation of the optic axis determines the polarization properties of the material.
