Customized Fine Grinding C-axis Optical Sapphire Rod Hardness 9.0
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.
