Frequently Asked Questions
Synthetic sapphire is a single crystal known for its high hardness, high strength, scratch resistance, high temperature resistance, chemical durability, and superior radiation stability.
Sapphire orientation refers to the angle of the sapphire crystal from its optical axis, known as the C-axis. The orientation affects the performance of the sapphire in terms of mechanical, optical, thermal, and birefringence properties.
The most common sapphire window orientation is the C-plane or 'Zero-degree' orientation. This is because it eliminates the inherent birefringent properties of the crystal and is the strongest and most mechanically symmetric orientation, making it ideal for optical applications.
A-plane sapphire windows have a uniform dielectric constant and highly insulating characteristics, making them suitable for semiconductor applications. They are also the hardest type of sapphire material, offering more scratch resistance than C-plane windows.
Sapphire windows are used for protecting cameras, detectors, and sensors due to their high hardness, strength, scratch resistance, and wide transmission bandwidths. They are also used in high-heat applications, electro-optics systems in defense and aerospace, and for transparent domes and underwater windows.
Sapphire windows can withstand extremely high temperatures, with a melting point of 2030°C, making them ideal for use in high-heat environments such as viewing windows on furnaces and high-temperature equipment.
Sapphire windows provide a wide bandwidth of transmission from 0.2 to 5 micrometers, making them suitable for various optical applications.
