Product Description

Overview

Large-size sapphire crystals are needed for optics and airborne windows with apertures of 600 mm and larger (for the medium-wave IR region of the spec-trum). At present, the only material used for the windows with a diameter greater than 300 mm is ZnSe.

Its ultimate strength reaches 69 MPa (10,000 psi). Large-size windows have a thickness of 20 mm or more, and such a thickness makes the win-dows heavy and expensive. Moreover, it gives rise to an essential optical scattering.

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.
