Key Selling Points

 

✅ Premium BK7 Glass Dome Lens – Professional Optical Grade Performance

Our bk7 glass dome lens is crafted from high-purity BK7 (K9 equivalent) optical glass, the global gold standard for precision optical components, with a uniform refractive index and ultra-low dispersion 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 advanced broadband AR coating achieves up to 99.5% light transmittance, eliminating surface reflection and refraction that blurs underwater footage, even in low-light deep-sea conditions.

 

✅ AR Coated Camera Dome – Reflection-Free Underwater Imaging

Our ar coated camera dome features a multi-layer anti-reflective coating precisely engineered for underwater use, 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. The coating is scratch-resistant and waterproof, withstanding long-term immersion in saltwater without peeling or degradation, making it the ideal choice for marine surveillance and underwater exploration.

 

✅ Underwater Camera Glass Dome – High Pressure & Waterproof Durability

Our underwater camera glass 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 fully sealed design ensures 100% waterproof performance. It’s also highly resistant to saltwater corrosion and UV radiation, extending the lifespan of your underwater camera system in harsh marine environments.

 

✅ OEM Optical Glass Dome – Fully Customized to Your Project

As a direct factory, we specialize in oem optical glass dome solutions, supporting full customization in diameter, curvature, thickness, edge design, and AR coating wavelength. Our bk7 hemisphere lens is available with integrated flanges for easy mounting, custom sealing for pressure vessels, and tailored AR coatings for specific underwater lighting conditions. Whether you need a micro 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 for every project.

 

✅ BK7 Hemisphere Lens for Marine & Scientific Applications

Our bk7 hemisphere lens is also perfect for marine scientific instruments, underwater lighting, and optical sensors, where precision and durability are critical. The high-purity BK7 glass offers excellent transmission across visible and near-infrared wavelengths, making it suitable for underwater spectroscopy, imaging, and measurement systems. The AR coating enhances light output for underwater lighting fixtures, while the pressure-resistant design ensures reliable performance in deep-sea environments.

 

✅ Factory Direct OEM Service & Strict Quality Control

As a direct factory, we offer unbeatable OEM pricing, fast production lead times, and strict quality control for all bk7 glass dome lens orders. Every k9 optical dome lens undergoes rigorous optical testing, pressure testing, and waterproof testing to ensure compliance with CE, RoHS, and ISO international standards.
