The main chemical component of sapphire is Al ? O ∝, which is originally transparent, clear, and has high strength and hardness, and is used in many production activities. Many mobile phones and camera lenses use sapphire lenses, which have higher shock resistance, airtightness, and strength than other materials. Sapphire glass is a synthetic sapphire composed of Al ? O ∝. The composition is the same as natural, and various colors can be produced by adding various chemical elements, such as blue when added to iron oxide and titanium oxide.

Sapphire is a wear-resistant material, but it cannot withstand strong impacts. Even objects with the same or higher hardness can scratch the surface of the material. Under annular static pressure, a sapphire glass sample with a thickness of 1 millimeter ruptured under a pressure of 161 pounds. Although sapphire has high scratch resistance, it is easily shattered under strong impact. Silicon carbide, artificial stone, and other materials used in many construction and decoration projects may leave scratches on the lenses during friction.

Sapphire lenses are primarily synthesized from pure alumina at high temperatures and then cut using diamond tools. From a chemical perspective, there is no difference between synthetic sapphire and natural sapphire. Since no other elements have been added, it is colorless and transparent, without the color 'blue'. The equipment used to test sapphire mirrors is the refractometer commonly used in jewelry appraisal, which measures the refractive index of the object being tested. Although sapphire glass is artificial, its refractive index naturally ranges from 1.76 to 1.77.

Sapphire lenses have been used by some mobile phone manufacturers for many years to protect the camera of the phone. We have the design and production foundation of sapphire window products, mature production and processing technology, and can produce various sapphire materials to provide the market with low and high transmittance sapphire products.
