Sapphire Window As Fingerprint Recognition

Product Description

Sapphire meniscuses (domes) shaped as hemispheres are used for making the heads of IR-radiation guided missiles. Here, sapphire is employed due to the com-bination of its sufficient transmission in the region of 3–5 m m and its mechanical strength. The temperature of the working article, and consequently the value of transmission and guiding accuracy, are defined by the outer surface roughness.

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.
