Product Introduction

2-inch Special Crystalline Sapphire Wafer A-plane (Double Side Polish)

Sapphire Substrate is a thin sheet made of single crystal sapphire (Al2O3) material. Due to its excellent physical and chemical properties, this material is widely used in optoelectronics, microelectronics and other high-tech fields. Sapphire substrates are highly transparent, hard, and chemically stable, making them key materials in many cutting-edge technologies.

Key Features:

  • Optical properties: Sapphire has high transparency and a stable refractive index and performs well in the ultraviolet to near-infrared spectral range. This makes sapphire substrates widely used in optics such as high-precision lenses and filters.

  • Thermal properties: Sapphire has a high thermal conductivity that dissipates heat effectively, while its low coefficient of thermal expansion allows it to maintain a stable size and shape at high temperatures. Therefore, sapphire substrates play an important role in high-power electronics.

  • Mechanical properties: Sapphires are known for their extreme hardness and flexural strength, which makes them resistant to wear and mechanical stress. This property makes it excellent in demanding working environments, especially in applications that require high abrasion resistance, such as watch surfaces and protective windows for high-precision instruments.High transmission to 85%

  • Chemical Resistance: Sapphire has excellent chemical resistance to most acids, bases, and solvents, and is able to remain stable in harsh chemical environments. This makes sapphire substrates widely used in chemical experiments and industrial production.

Applications:

Our 2-inch sapphire wafer A-plane is designed for a wide range of applications, including:

  • Optical windows: Sapphire's high transparency and resistance to wear make it an ideal material for high-performance optical windows, which are widely used in scientific instruments, aerospace, and military equipment.

  • Lenses & Filters: Sapphire is used in high-precision lenses and filters due to its stable optical properties and mechanical strength, which can provide clear and stable optical performance in harsh environments.

Conclusion:

Choose our 2-inch sapphire wafer A-plane for your next project to benefit from its unparalleled quality, versatility, and performance. Whether you are working in the fields of electronics, optics, or advanced manufacturing, this sapphire wafer will meet and exceed your expectations, providing a reliable foundation for innovation and excellence in your applications.
