Large Customizable Optical Domes | Sapphire & BK7 by Felix Glass

Our large customizable optical domes are high-performance protective and imaging components designed for demanding industrial, underwater, and aerospace applications. Available in sapphire, BK7, fused silica, or K9 optical glass, these domes are built to handle extreme conditions while delivering ultra-high light transmittance and minimal distortion.

With diameters ranging from 5mm to 300mm, we offer full customization of size, thickness, curvature, and coatings, including AR/IR/UV/AF multi-layer options. The hemispherical, spherical, or half-sphere shapes provide a wide-angle field of view, making them ideal for large-format surveillance systems, deep-sea ROVs, and high-pressure industrial sensors.

Sapphire domes feature a 9 Mohs hardness rating for exceptional scratch and impact resistance, while BK7 options offer a cost-effective solution for large-scale projects. Both materials are pressure-resistant, waterproof, and corrosion-resistant, ensuring long-term durability in harsh environments. Our strict quality control ensures high precision and surface accuracy, with fast prototyping and mass production available for OEM/ODM orders.
