substrates wafers for GaN epitaxial growth；
TYPICAL CHOICES FOR PART ORIENTATION:
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.
Sapphire is one of the hardest materials, and possesses very good
transmission during the range of visible and near IR spectrum.It is
widely used for led substrates for GaN Epitaxial growth ；and also
as optical window in infrared and far infrared military equipments,
apparatus and instruments of satellite and space technology, and
navigation and spaceflight, such as night infrared scope/sight and
night vision camera, etc.The sapphire crystal window is intensively
applied in high-tech fields.
