Detail Information
Felix Glass specializes in high hardness sapphire optical domes, designed for demanding applications where scratch resistance and impact protection are critical. These scratch resistant domes are made from single crystal sapphire (Al₂O₃), offering exceptional hardness, chemical stability, and long-term durability for use in underwater, industrial, aerospace, and medical environments.
✅ Key Features of Our High Hardness Sapphire Optical Domes
- Material: Single crystal sapphire (Mohs 9), second only to diamond in hardness, making these impact resistant domes ideal for high-wear applications.
- Optical Performance: High light transmittance across visible and near-infrared spectrum, ensuring clear visibility for camera and sensor systems.
- Optional Coatings: Anti-reflection (AR) coatings available to enhance light transmission, reduce glare, and improve optical system efficiency.
- Customization: Custom sizes, shapes, radii, and tolerances available to meet your exact project requirements, from small camera domes to large industrial viewports.
- Environmental Resistance: Excellent resistance to high temperatures, corrosion, and impact, suitable for use in harsh marine, industrial, and aerospace conditions.
✅ Common Applications
- Underwater camera domes and ROV protection, where water pressure, impact, and corrosion resistance are essential.
- Security and surveillance sensors, offering long-term protection against scratches, vandalism, and environmental damage.
- Aerospace and industrial protection systems, providing reliable performance in extreme conditions.
- Medical imaging equipment and scientific instruments, where biocompatibility, clarity, and durability are critical.
- Industrial automation and inspection equipment viewports, protecting internal components while maintaining clear optical access.
All our sapphire optical 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.
If you have any questions about our high hardness sapphire domes, or need help selecting the right specifications, coatings, or sizes for your application, please contact our technical support team. We are happy to provide professional advice and a free quote based on your exact requirements.
