Why Choose sapphire crystal?
Chemically, sapphire is single crystal aluminum oxide (Al2O3), and is useful in a transmission range from 0.2 - 5.5µm
Sapphire crystal is extremely hard and scratch resistant. It is the hardest of the oxide crystals, being the next strongest material to diamond.
Because of its hardness (second only to Diamond), Sapphires are used in industrial applications such as components for watch crystals and movement bearings, scientific instruments, high-durability windows, and insulating substrates in special purpose solid state electronics
