Al2O3 Single Crystal 99.999% Sapphire Dome Infrared Light Optical Window Mohs9
Description of sapphire dome:
A sapphire dome is a transparent, dome-shaped structure made from sapphire, which is a crystalline form of aluminum oxide (Al2O3).
Sapphire is known for its exceptional hardness and optical clarity, making it an ideal material for various applications that require superior
strength and excellent optical properties.
Sapphire domes are typically used in aerospace, defense, and high-end optical systems where protection, durability, and optical performance
are critical.
Features of sapphire dome:
Sapphire is one of the hardest known materials, second only to diamond on the Mohs hardness scale.
The hardness of sapphire provides excellent resistance to abrasion, making sapphire domes less prone to surface damage and maintaining their optical quality over time.
Sapphire has good thermal conductivity, which enables efficient heat dissipation and thermal management in applications where temperature control is crucial.
Sapphire has excellent mechanical strength, allowing it to withstand high-pressure conditions and protect sensitive components from impacts and debris.
Sapphire is highly resistant to chemical corrosion, making it suitable for use in harsh environments and applications involving exposure to corrosive substances.
Sapphire has a high melting point of around 2040 degrees Celsius, enabling it to withstand high-temperature environments without deformation or degradation.
