Rectangular sapphire window is a double planar circular optical sapphire glass commonly used as a protective window for sensors and detectors. Sapphire phone panels used for mobile phones will not change the magnification of the system. Window coatings include various optical coatings such as anti reflective coatings, high reflective coatings, spectral coatings, metal coatings, etc. Broadband anti reflective coatings can be used for ultraviolet, visible, near-infrared, and mid infrared.

1. Basic characteristics

Sapphire (molecular formula: Al2O3) single crystal is an excellent multifunctional material with high temperature resistance, good thermal conductivity, high hardness, transparency to infrared radiation, and good chemical stability. Sapphire mobile phone panels have high hardness, scratch resistance, and high temperature resistance, with a spectral range of 150-3500nm.
