Sapphire is composed of alumina, and its crystal structure is hexagonal lattice structure.
Synthetic sapphire common application facets are A-Plane,C-Plane, and R-Plane. Due to the wide optical penetration band of sapphire, it has good light transmission from near ultraviolet (190nm) to mid-infrared. Therefore, it is widely used in optical components, infrared devices, high-intensity laser lens materials.
Sapphire also has the characteristics of high sound velocity, high temperature resistance, corrosion resistance, high hardness, high light transmittance, high melting point (2045℃), etc., so it is often used as a material for photoelectric components.
