Calcite can be easily cleaved along three distinct planes, making it possible to produce rhombs of the form shown in Fig. 1. The optic axis, going in the HI direction, makes equal angles with all three faces at point H. Any plane, such as DBFH, which contains the optic axis and is perpendicular to the two opposite faces of the rhomb ABCD and EFGH is called a principal section.
