Sapphire glass window panel

High speed rail upper sectionDisplay windowWe need to use cover glassGlass window panelBut these glasses need to be able to withstand it High speed impact with a speed of 200 kilometers per hour or above; Secondly, inOptical transparencyThe requirements are relatively high, and it is necessary to ensure the clarity of the window vision; Finally, operation and maintenance should be convenient.

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.

Sapphire camera lens protective glass

During high-speed rail operation, outdoor testing camera lenses often face challengesDust, flying stones, raindrops, hailWaiting for the high-speed impact of foreign objects (with a speed of over 400 kilometers per hour), in addition to resistingHigh speed vibrationThe risk of damage caused.sapphire glassThe Mohs hardness reaches level 9, and the fracture toughness is 3-4 times that of ordinary glass, which can effectively resist the high-speed impact of foreign objects and protect precision imaging components from damage.
