Abstract

Two cases are considered: 1. The property of crystals with an optic axial angle 2V=90°C. 2. Determination of the optical sign of a biaxial crystal on the universal stage, when no optic axis is visible. It is possible to determine the position of the obtuse and acute bisectrix of the optic axial angle, and therefore the optical sign of the crystal.
