BK7 K9 Optical Glass Dome for Professional Underwater Cameras

Our BK7 K9 Optical Glass Dome are precision-engineered protective lenses designed for professional underwater photography and cinematography systems. Made from high-quality optical glass, these domes are optimized for use with large-format underwater housings, delivering ultra-high light transmittance and minimal distortion for sharp, clear imaging at any depth.

The spherical shape corrects for water refraction, allowing professional cameras to capture a wide, undistorted field of view without vignetting or color fringing. We offer custom diameters (1mm-150mm) and optional AR/IR/UV/AF coatings to enhance light transmission, reduce glare, and protect the lens from scratches and water spots. These domes are pressure-tested for deep-sea use, ensuring reliable performance in harsh marine environments.
