Custom Mohs 9 Hardness Sapphire Optical Dome

Felix Glass produces custom high-hardness sapphire optical domes, engineered for environments requiring maximum durability and optical performance. These custom sapphire domes are widely used in demanding applications such as underwater cameras, aerospace sensors, and industrial equipment housings, where both optical clarity and mechanical strength are critical.

✅ Core Advantages of Our Custom Sapphire Domes

- Ultra-hard single crystal sapphire (Mohs 9), offering exceptional scratch resistance and impact resistance, far superior to glass or plastic alternatives.

- Excellent UV-VIS-NIR broadband transmittance, up to 99% with anti-reflection (AR) coating, ensuring clear visibility and optimal light transmission.

- Optional AR/AF/DLC coatings available to meet specific optical requirements, reducing glare, smudges, and environmental interference.

- Custom sizes, shapes, radii, and tolerances are available to fit your exact project specifications, from small camera domes to large industrial viewports.

- High-temperature and chemical resistance, making these sapphire domes suitable for use in harsh industrial, marine, and aerospace environments.

✅ Common Applications

- Underwater camera and ROV protection domes, where water pressure, impact, and corrosion resistance are essential.

- Aerospace and military sensor housings, requiring reliable performance in extreme conditions.

- Industrial automation and inspection equipment viewports, providing clear optical access while protecting internal components.

- Medical and scientific instruments, where biocompatibility, clarity, and durability are critical.

- Surveillance and security cameras, offering long-term protection against scratches, vandalism, and environmental damage.

All our custom sapphire domes undergo strict quality control before delivery, including optical transmittance testing, surface quality inspection, and dimensional accuracy verification. We also offer flexible production schedules to meet both small-batch custom orders and large-volume bulk orders.
