High-Pressure Silica Glass Optical Dome Lens for Submersible Camera Housings



1. Material Composition

  • 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.


2. Key Properties

  • 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.


3. Core Functions

  • 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.


4. Applications

  • 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.


5. Advantages Over Acrylic/Polycarbonate Lenses

  • 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.


6. Target Industries

  • 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.
