Sapphire Optical Components

Sapphire optical domes are precision hemispherical optical components designed to protect cameras, sensors, and imaging systems while maintaining excellent optical performance under extreme operating conditions. Manufactured from synthetic single-crystal sapphire, these domes provide outstanding mechanical strength, superior scratch resistance, and long-term environmental durability. Compared with conventional optical glass, sapphire offers significantly higher hardness, pressure resistance, and service life in demanding applications. Key Features • Mohs 9 hardness for exceptional scratch resistance • High optical transmission from UV to infrared wavelengths • Excellent pressure resistance for underwater systems • Superior chemical and corrosion resistance • Wide operating temperature range • Optional AR and custom optical coatings Applications Sapphire optical domes are widely used in: • Underwater cameras and deep-sea robotics • Marine monitoring and surveillance systems • Aerospace imaging equipment • Defense and military optical systems • Industrial machine vision systems • Scientific and research instruments Custom Manufacturing Felix Glass provides OEM and ODM sapphire dome manufacturing with customizable diameter, thickness, curvature, surface quality, coatings, and precision tolerances. Engineering support is available from prototype development to mass production.

Felix Glass is a professional manufacturer of high-precision sapphire optical components, including sapphire windows, sapphire lenses, sapphire rods, and custom sapphire optics. Made of high-quality single-crystal alumina, our sapphire parts feature exceptional hardness, broad-spectrum optical transmittance, superior thermal stability, and chemical inertness. They outperform ordinary glass in high-pressure, high-temperature, and corrosive scenarios, making them ideal for aerospace, medical, industrial laser, and semiconductor applications. Each component is precision polished and can be custom coated for anti-reflection, anti-fingerprint, or high-temperature resistance. We offer full drawing-based customization, strict quality control, and flexible MOQ for both prototypes and mass production.
