C-axis (0001) orientation 12inch diameter 300mm with notch DSP Sapphire Substrate wafers thickness 1.5mm C-a

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.

Application

The 8-inch DSP sapphire crystal window with a 3mm thickness is an ideal solution for a wide range of demanding applications requiring durability, clarity, and high-temperature resistance. Sapphire wafers of this size and specification are particularly suited for advanced optical systems, precision instruments, and industrial environments where extreme conditions are present.

Thanks to sapphire’s Mohs hardness rating of 9, these crystal windows provide exceptional scratch resistance, making them perfect for use in high-precision machinery, protective windows for optical sensors, and scientific instruments where surface integrity is critical. Moreover, the 3mm thickness ensures robustness without compromising transparency, making it a versatile material for applications in high-pressure environments or where mechanical stress is a concern.

Sapphire’s thermal stability, capable of withstanding temperatures up to 1950°C, makes these wafers ideal for use in high-temperature processing chambers, semiconductor manufacturing, and gas processing systems. Additionally, its excellent chemical resistance ensures that it remains unaffected by harsh environments, allowing it to be used in industrial or scientific settings where other materials would fail.

In summary, the 8-inch DSP sapphire crystal window is an optimal choice for high-performance applications requiring strength, thermal resilience, and optical clarity.
