Sapphire (Al2O3) is one of the hardest minerals and optical materials available for use in the range from UV up to 5µm. Making it ideal as a protective window for camera systems.
Sapphire is grown by various methods from seed samples. Sapphire can be polished to a high standard, but as it is the second hardest mineral on Earth it must be subject to high forces to polish. Sapphire is inert and resistant to attack from most processing environments, such as hydrofluoric acid. Sapphire has a melting point over 2000°C with a high thermal conductivity makes it suitable for use in harsh environments.
The benefit of using Sapphire over other materials for high pressure underwater cameras, are that Sapphire windows can be offered up to 65% thinner than Fused Silica Windows, and are much more scratch resistant as well.
