Special Orientation SSP/ DSP A-axis <11-20> R-axis <1-102> M-axis<10-10> 2inch 3inch 4inch 6inch sapphire 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.
