Upgrade your underwater imaging systems with our premium BK7/K9 flanged dome lens, the ultimate high-precision optical solution engineered for underwater cameras, ROVs, and subsea surveillance. These flanged dome lenses combine industry-leading optical clarity, extreme hydrostatic pressure resistance, and full waterproof performance, while advanced broadband AR coating eliminates reflection and refraction for crystal-clear deep-sea imaging.

Material options: BK7 / K9 Optical Glass / Fused Silica

Custom coatings: AR / Anti-Reflective / AF Anti-Fingerprint

Fast lead time: 3-5 days for samples, 10-15 days for bulk orders

✅ Key Features

- Premium BK7/K9 Construction: Made from high-purity BK7 optical glass, offering ultra-low dispersion and uniform refractive index for zero optical distortion

- Integrated Flanged Design: Precision-engineered flanged edge enables sealed, hassle-free mounting for leak-proof underwater performance

- High Pressure Resistance: Designed to withstand extreme hydrostatic pressure, ideal for deep-sea ROVs and high-pressure camera housings

- AR Coated Clarity: Multi-layer anti-reflective coating eliminates glare, ghosting, and refraction, delivering sharp images in low-light deep-sea conditions

- Customizable Options: Available in custom diameters, radii, thicknesses, and flange sizes to fit your exact camera housing requirements

✅ Common Applications

- Underwater ROVs and subsea inspection systems

- Deep-sea cameras and marine research equipment

- Commercial underwater surveillance and security systems

- Industrial subsea monitoring and offshore platforms

- Scientific research and oceanographic imaging systems

All our flanged dome lenses undergo strict quality control, including pressure testing, optical performance testing, and dimensional accuracy verification. We support small custom orders and large-volume production, with flexible lead times to meet your project needs.
