Sapphire windows are used in Semiconductor process chambers as well as many other high vacuum applications. Process environments that would rapidly erode quartz windows do not affect single crystal sapphire. While the service life of quartz windows can be limited, in many cases sapphire windows can be used indefinitely.
Sapphire is also used in aerospace to protect onboard imaging, and sensing flight vision systems while allowing broadband transmission. Sapphire is compatible with Ultraviolet, Visible, and mid-wave infrared sensors.
Sapphire is extremely hard and abrasion-resistant which makes it the first choice for protection against high-velocity projectiles. More information about this specific use and the properties that make Sapphire the first choice for Safety Windows.
Flat Windows - The world's largest sapphire windows available
Sapphire sheets are manufactured using Edge Fed Growth technology, a process that grows single-crystal sapphire to near-net shapes, thus reducing post-growth processing. EFG™ technology enables the production of large windows (1 ft x 3 ft), the shape and size of a sapphire crystal to be controlled during its formation.
