Sapphire Phone Camera Lens

Product Overview

Sapphire camera lenses are crafted from high-purity synthetic sapphire crystal (Al₂O₃), specifically designed for precision optical systems in high-end camera modules, smartphones, security surveillance, industrial equipment, and automotive imaging. Renowned for their exceptional physical properties and optical performance, sapphire lenses are the ideal choice for high-definition imaging and long-term durability in harsh environments, meeting the dual demands of durability and image quality in consumer electronics and industrial applications.

Key Advantages

  1. Superior Scratch & Wear Resistance

    • Mohs hardness of 9 (second only to diamond), effectively resisting scratches from sand, metal tools, and sharp objects.

    • No additional protective coating required; maintains pristine clarity over extended use.

  2. High Light Transmittance & Low Reflectance

    • Visible light transmittance ≥90%, ensuring accurate color reproduction and minimizing light loss.

    • Optional anti-reflective (AR) coating to reduce glare and ghosting, enhancing low-light imaging.

      • 1

  3. Extreme Environment Adaptability

    • Operating temperature range: -50°C to 800°C, resistant to thermal shocks and rapid temperature changes.

    • Chemically inert to acids, alkalis, oils, and solvents, ideal for industrial or outdoor applications.

  4. Ultra-Thin Precision Design

    • Customizable thickness (0.3mm–3.0mm) to fit miniaturized camera modules.

    • Ultra-high flatness (λ/4@632.8nm) and low birefringence for edge-to-edge image sharpness.
