Sapphire windows are applied in gas cryostats and helium microstats with D (12…25) × 2 mm, sealed in metallic flanges or gasketed in the sockets of devices.
Copper gaskets or indium wires provide a vacuum-tight seal to the cryostat. Windows with a wedge of 1° and 3° are used in laser engineering as partially reflecting mirrors or prisms for laser beam control.
Now sapphire is also used for the scanner windows of cash registers that read bar codes.
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.
