High-Pressure Silica Glass Optical Dome Lens for Submersible Camera Housings
Silica Glass: High-purity fused silica/quartz glass with ultra-low thermal expansion and exceptional optical clarity.
Housing: Titanium or marine-grade aluminum alloy, anodized for corrosion resistance.
Coatings: Anti-reflective (AR) coatings (350–700 nm range) and hydrophobic layers to repel water droplets.
Seals: Precision-engineered silicone O-rings and epoxy bonding for waterproof integrity.
Extreme Pressure Resistance: Withstands depths exceeding 1,000 meters (100+ bar pressure).
Optical Purity: >99% light transmission with minimal distortion or chromatic aberration.
Thermal Stability: Operates in -50°C to 300°C ranges, resisting thermal shock.
Chemical Durability: Immune to saltwater, oils, and acidic/alkaline marine environments.
Mechanical Strength: Scratch-resistant surface (Mohs hardness ~7) and impact-tested design.
Pressure Equalization: Dome shape distributes external pressure evenly, preventing housing collapse.
Light Transmission: Maximizes light capture in low-visibility underwater environments.
Image Clarity: Minimizes spherical aberration for sharp, wide-angle photography/videography.
Environmental Protection: Shields cameras from abrasives, biofouling, and high-pressure water ingress.
Deep-Sea Exploration: ROV/AUV camera housings for marine biology and geology research.
Underwater Cinematography: 4K/8K video rigs for documentaries and film production.
Offshore Industrial Inspections: Monitoring pipelines, rigs, and subsea infrastructure.
Scientific Diving: Housing for underwater archaeology and ecological surveys.
Aquaculture: Monitoring fish farms and underwater equipment health.
Superior Depth Tolerance: Maintains structural integrity at depths where plastics deform.
Optical Longevity: Resists clouding/yellowing from UV exposure or biofilm growth.
Temperature Resilience: No warping in polar or hydrothermal vent environments.
Enhanced Durability: 10x more scratch-resistant than polymer alternatives.
Marine Technology OEMs: Custom housings for submersibles and ROVs.
Underwater Camera Manufacturers: High-end rigs for professional divers and filmmakers.
Oil & Gas Companies: Inspection tools for offshore drilling operations.
Research Institutions: Equipment for oceanographic studies and deep-sea missions.
