Custom Sapphire Cover Glass for Camera, Fingerprint & Scanner Applications

Sapphire Cover Glass is one of the most durable optical protection materials available today. Manufactured from high-purity single crystal sapphire (Al₂O₃), it combines exceptional hardness, optical transparency, thermal stability, and chemical resistance in a single material.

Unlike conventional tempered glass, sapphire cover glass provides superior protection against scratches, impacts, and environmental wear while maintaining excellent light transmission. These advantages make it the preferred solution for camera lenses, biometric sensors, barcode scanners, laser systems, and high-end electronic devices.

Whether for consumer electronics or industrial equipment, sapphire cover glass helps extend product lifespan, improve reliability, and maintain optical performance even under continuous use.

Key Features

Superior Scratch Resistance

With a Mohs hardness of 9, sapphire is second only to diamond in hardness. It offers exceptional protection against scratches from keys, metal objects, dust particles, and everyday wear.

Excellent Optical Clarity

Sapphire provides outstanding optical transmission across visible and infrared wavelengths, ensuring clear imaging, accurate sensing, and reliable signal transmission.

High Impact Durability

The high mechanical strength of sapphire helps protect sensitive optical and electronic components from physical damage and harsh operating conditions.

Thermal Stability

Sapphire maintains stable performance under elevated temperatures, making it suitable for high-power optical devices and demanding industrial environments.

Chemical Resistance

Resistant to acids, alkalis, solvents, and environmental corrosion, sapphire cover glass delivers long-term reliability in both indoor and outdoor applications.
