Sapphire material has excellent optical and mechanical properties, such as high strength, hardness, wear resistance, unique high temperature resistance, acid and alkali corrosion resistance and high dielectric properties, etc., in a wide spectrum (250-5500nm) with high transmittance.
Therefore, sapphire lens can be used as optical surface, corrosion resistant surface or precision imaging optical instrument and focusing optical instrument accessories, common can be used for high-grade clocks and watches, jewelry, and all kinds of glasses, transparent lamps and lanterns and goggles.
