The core advantage of sapphire glass as a window panel is reflected in its uniquePhysics, Chemistry, and OpticsIn terms of performance:

one
Physical protection


Ultra high hardness

Sapphire has a Mohs hardness ofLevel 9(second only to diamond), its scratch resistance is 120 times that of ordinary glass, and it can resist surface damage caused by daily hard object friction; The bending strength reaches 400-500MPa, the fracture toughness is 3-4 times that of ordinary glass, and the resistance to impact fracture is significantly improved.


Extreme environmental adaptability

Sapphire glass can withstand severe temperature differences ranging from -196 ℃ to 2000 ℃,Stable and deformation free structure under high temperature environmentStrong resistance to chemical corrosion, resistant to acid, alkali, and de icing agents, and can maintain integrity even after long-term exposure to harsh environments.



two
optical performance


Broad spectral translucency

Wide light transmission range, with a visible light transmittance of over 83% (up to 90% after coating), and clear imaging without color cast.


Scalability of optical functions

Support surface coating enhancement: AR anti reflective film,The transmittance can be greatly improvedReduce glare interference.
