high quality Sapphire Window As Fingerprint Recognition

Product Description

According to Oxford Instruments Superconductivity, the place occupied by sap-phire windows in comparison with those made of other materials can be repre-sented by the diagram shown . The diagram allows selection of a window material that satisfies the required working conditions. Now sapphire is also used for the scanner windows of cash registers that read bar codes.

Windows with a wedge of 1° and 3° are used in laser engineering as partially reflecting mirrors or prisms for laser beam control. 

Sapphire could be used as windows: 1.mobile phone screens; 2. lens; 3. fingerprint recognition; 4. Wearable equipment windows and so on, because of  its unique advantages including: high sensitivity, scratch resistance, abrasion resistance, high temperature resistance, high pressure resistance, good chemical stability, and corrosion and deliquescence resistance.
