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.
Superior Scratch ResistanceWith 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.
Sapphire provides outstanding optical transmission across visible and infrared wavelengths, ensuring clear imaging, accurate sensing, and reliable signal transmission.
The high mechanical strength of sapphire helps protect sensitive optical and electronic components from physical damage and harsh operating conditions.
Sapphire maintains stable performance under elevated temperatures, making it suitable for high-power optical devices and demanding industrial environments.
Resistant to acids, alkalis, solvents, and environmental corrosion, sapphire cover glass delivers long-term reliability in both indoor and outdoor applications.
Designed for smartphone cameras, automotive cameras, surveillance systems, drones, and machine vision equipment. Sapphire protects optical lenses from scratches while maintaining image quality.
Provides a durable interface for fingerprint recognition modules. Its excellent dielectric properties support fast and accurate biometric identification.
Suitable for laser projectors, industrial lighting systems, and optical engines requiring high-temperature resistance and superior optical transparency.
Widely used in barcode scanners, logistics equipment, self-checkout systems, and industrial identification devices where continuous scanning performance is essential.
Protects infrared sensors, LiDAR systems, optical detectors, and precision instruments operating in demanding environments.
