Special Shap Small Mini Sapphire Lens Protector

Production description:

Sapphire Lens Protector can be customized bu our customer, Mini size fit for samll watches or other equipment.Sapphire crystal (sapphire glass) generally refers to synthetic sapphire, generally used in the manufacture of the watch glass .It is resistant to wear with tungsten titanium alloys and high-tech ceramics. but sapphire materials can wear resistance, withstand the strong impact, and some of the same or higher hardness of the material.

Synthetic Optical Sapphire has no colouration and with a selection of grades of Sapphire available, transmission ranges from 170nm to 6 microns.Sapphire Windows are manufactured from single crystal sapphire, Standard grade Sapphire material is grown by Verneuil and Czochralski methods, whereas higher quality Sapphire is manufactured by the Kyropulus growth method.Sapphire is able to be cut thinner than alternative crystals due to its structural durability. Chemically, sapphire is single crystal aluminum oxide (Al2O3), and is useful in a transmission range from 0.2 - 5.5µm Sapphire crystal is extremely hard and scratch resistant. It is the hardest of the oxide crystals, being the next strongest material to diamond.

because of their extreme surface hardness, high thermal conductivity, high dielectric constant and resistance to common chemical acids and alkalis. Sapphire Lens Protector is also very popular among smart phone.
