Precision optical domes engineered for underwater cameras, ROVs, AUVs, subsea inspection, marine monitoring and underwater imaging systems. Custom materials, dome geometry, optical polishing and AR / BBAR coatings according to your optical and mechanical requirements. Sapphire • Fused Silica • Quartz • BK7 / H‑K9L • ZnSe • ZnS • Ge • Si An underwater optical dome must work as both an optical interface and a protective component. Material selection, dome geometry, surface quality, optical distortion, reflection loss and hydrostatic loading all affect system performance. The substrate must match wavelength, transmission, mechanical strength, environment and cost. Common choices include sapphire, fused silica, quartz, BK7, H‑K9L and borosilicate; specialized IR materials serve specific infrared systems. Dome radius, diameter, wall thickness, edge geometry and mounting interface directly affect optical performance and mechanical integration. An improperly designed or manufactured dome can reduce image quality, particularly for wide‑angle underwater cameras. External pressure increases with depth. Geometry, wall thickness, material and housing structure should be evaluated for the operating environment. Water, coating and substrate interfaces introduce reflection losses. Suitable AR or BBAR coatings can improve transmission in specified bands. Scratches, pits, waviness and polishing defects may reduce contrast, cause scattering and affect imaging performance. Salt deposits, corrosion environments and repeated cleaning require material, coating and sealing design to be considered together. Custom low‑volume prototypes require dimensional repeatability for accurate housing integration and subsequent production.
