in addition bi-axial, 1833; see bi- + axial.
having two axes
- Having two axes; as, biaxial polarization.
(a.) Having two axes; as, biaxial polarization.
In this line of investigation the prime importance belongs to the discovery (1) of the connexion between the refractive index and the polarizing angle, (2) of biaxial crystals, and (3) of the production of double refraction by irregular heating.
