TYPICAL CHOICES FOR PART ORIENTATION:
Why Sapphire?
Zero Degree: The direction of view is parallel to the optical axis of the crystal 
90 Degree: The direction of view is perpendicular to the optical axis of the crystal
C-Axis: In a rod, the direction along its length. In a window, the direction perpendicular to the face.
M-Plane: The plane containing the optic axis (C) and inclined 30 degrees to the A-axis
A-Plane: The plane that is perpendicular to the A-axis, containing the C-axis
R-Plane: A plane inclined 57.5667 degrees to the optic axis in the same zone as the M-plane.
Random: There is no specified relationship between the part and the crystalline orientation. The part is manufactured without concern about orientation.
