Sapphire is a hard crystal, it is widely used for watches, mobile phones, beauty equipment, lasers, LED applications, and more.
Sapphire Windows are manufactured from single crystal sapphire, making them ideal for demanding applications (such as laser systems) because of their extreme surface hardness, high thermal conductivity, high dielectric constant, and resistance to common chemical acids and alkalis. Sapphire is the second hardest crystal next to diamonds. Because of its structural strength, sapphire windows can be made much thinner than other common dielectric windows with improved transmittance. Chemically, sapphire is single crystal aluminum oxide (Al₂O₃), and is useful in a transmission range from 0.2 - 5.5µm.
