Description

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. As a professional manufacturer of flanged edge optical glass dome, we specialize in 100% custom underwater camera flanged dome solutions, crafted from high-purity BK7/K9 optical glass with an integrated precision flanged edge for sealed, hassle-free mounting. Our custom BK7 hemisphere lens combines 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. Whether you need a flanged dome for a commercial underwater camera, a high-pressure hemisphere for a deep-sea ROV, or a custom optical lens for marine scientific instruments, we deliver factory-direct quality that exceeds global optical and marine engineering standards.
 
Key Selling Points
 
✅ Premium BK7/K9 Flanged Dome Lens – Professional Optical Grade
Our BK7 K9 flanged dome lens is made of high-purity BK7 (K9 equivalent) optical glass, the global gold standard for precision optical components, with ultra-low dispersion and uniform refractive index for zero optical distortion. Unlike ordinary soda-lime glass, BK7/K9 delivers exceptional light transmission and optical consistency, ensuring accurate color reproduction and sharp imaging for underwater cameras. The integrated flanged edge enables direct, sealed mounting to camera enclosures, eliminating the need for extra adapters and ensuring a watertight seal for deep-sea use.
✅ AR Coated Flanged Glass Dome – Reflection-Free Underwater Imaging
Our AR coated flanged glass dome features a multi-layer anti-reflective coating precisely engineered for underwater environments, minimizing light loss at the air-glass and glass-water interface. This eliminates glare, ghosting and refraction distortion, ensuring the camera’s field of view remains accurate and images stay razor-sharp from edge to edge, even in low-light deep-sea conditions. The coating is scratch-resistant and saltwater-proof, withstanding long-term immersion in saltwater without peeling or degradation.
✅ Underwater Camera Flanged Dome – High Pressure & Waterproof Durability
Our underwater camera flanged dome is precision-engineered to withstand extreme hydrostatic pressure, making it suitable for deep-sea ROVs, submersibles and long-term underwater installations. The tempered BK7/K9 construction provides superior impact and scratch resistance, protecting the camera lens from marine debris and physical damage, while the flanged edge ensures a 100% watertight seal with the housing. It is also highly resistant to saltwater corrosion and UV radiation, extending the lifespan of your underwater camera system in harsh marine environments.
✅ Custom BK7 Hemisphere Lens – Fully Tailored to Your Project
As a direct factory, we support full customization of custom BK7 hemisphere lens in diameter, curvature, thickness, flange size and AR coating wavelength. Whether you need a micro flanged dome for a mini underwater camera or a large hemisphere for a deep-sea exploration ROV, we deliver tight tolerance control and consistent optical performance. We also offer optional fused silica material for high-temperature and UV applications, meeting the exact technical needs of your underwater project.
✅ Factory Direct OEM Service & Strict Quality Control
As a direct factory (felix glass), we offer unbeatable OEM pricing, fast production lead times and strict quality control for all flanged BK7/K9 dome lens orders. Every product undergoes rigorous optical testing, pressure testing and waterproof testing to ensure compliance with CE, RoHS and ISO international standards. We support small-batch prototype orders and large-scale mass production, making us the trusted partner for global underwater camera brands, ROV manufacturers and marine scientific research institutions worldwide.
