Saint-Gobain is the world leader in curved sapphire windows. Curved Sapphire is available in radial sizes ranging from 2” Radius to 25” Radius with chord lengths from 2.5” to 9” and thicknesses from .04” to .30” (click on illustration below).
Synthetic sapphire properties make it the material of choice for a variety of applications ranging from optical sapphire windows for aerospace sensor systems to tubes, pins, rods, and lenses for industrial and semiconductor markets. Sapphire's unique properties make it a cost-effective solution where high performance and long life are critical, including extreme conditions such as high-temperature, high-pressure, or harsh chemical and physical environments.
One of the hardest materials in existence, sapphire is virtually scratch-proof which helps it maintain its integrity in demanding physical environments. It has a melting point of over 2000 °C, making it ideal for high-temperature applications. It is chemically inert and easily withstands harsh chemicals such as fluorine plasma and other industrial gasses and fluids, with no particle generation. In addition, sapphire can transmit ultraviolet, visible, and infrared light as well as microwaves, a range broader than most materials.
