Optical elements made of sapphire are also widely used in the lens industry, including any mobile phone lens and camera lens; Sapphire is mostly in the form of crystal, which is very suitable for making optical components. Among some lens components, sapphire is also very needed. Like this sapphire crystal material, it can make optical components of various sizes, shapes and directions, and this optical component has no scattering, It is very suitable for lens applications. Some sapphire crystals have very different characteristics and can cover strong ultraviolet rays or other medium infrared rays. If this optical element is used in the lens industry, it has ultra-high hardness characteristics, high transmittance, high chemical reaction stability and thermal stability, and has optical, physical Chemistry and other advantages have been widely used in aerospace or industrial fields. For example, more or less lens materials in our life have sapphire optical components; It is so excellent, but it has not been developed and applied in some detailed fields. It may have some limitations. It can still show its advantages when used in large industries.
