Flanged Optical Dome Port | Integrated One-Piece Flange Subsea Camera Dome
Our flanged optical dome ports feature an integrated one-piece flange, precision machined together with the hemispherical dome. Built for deep sea ROV, AUV and underwater camera housing, this all-in-one design simplifies assembly, supports O-ring watertight sealing and eliminates separate retaining rings. Rated options for 3000m or 7000m water depth, diameter 20–60 mm. No stock, fully custom fabrication.
Key Features of Flanged Optical Dome Port
- One-piece integrated flange + dome, no separate clamping ring required
- Depth rating optional: 3000m (300 bar) / 7000m (700 bar)
- Material: JGS1 Fused Silica / C-axis Sapphire (for 7000m)
- Diameter range: 20 mm ~ 60 mm
- Precision O-ring groove / sealing step on flange face
- Optional broadband AR anti-reflection coating (VIS / NIR)
- FEA pressure simulation + hydrostatic pressure test & certificate available
- Easy bolt mounting, excellent seawater corrosion resistance
Typical Applications
- Deep sea ROV / AUV camera imaging systems
- Subsea inspection camera housings
- Marine scientific observation instruments
- Offshore underwater visual monitoring equipment
- Subsea LiDAR optical windows

Material Selection Guide for Flanged Dome
JGS1 Fused Silica is preferred for 3000m flanged dome, balanced strength, optical performance and cost. For 7000m ultra-deep working condition, C-axis cut Sapphire is the primary recommendation due to extreme compressive strength. Custom thick-wall fused silica is available as alternative with mandatory FEA validation. BK7 and Acrylic are not suitable for 7000m service.
Material Selection Chart
| Material | Max Rated Depth | Hydrostatic Resistance | Seawater Resistance | Optical Performance | Cost Level | Recommended Use Case |
|---|---|---|---|---|---|---|
| C-axis Sapphire | 7000m+ | Outstanding | Outstanding | High hardness, scratch resistant, stable transmission | High | Primary for 7000m flanged subsea dome, long-term deep immersion |
| JGS1 Fused Silica | 3000m+, 7000m with reinforced wall & FEA | Excellent | Excellent | High transmittance, low birefringence | Medium | Default choice for 3000m flanged dome, 7000m alternative option |
| BK7 Optical Glass | ≤3000m (strict annealing) | Good | Good | Good visible band transmission | Low | Cost-sensitive 3000m projects, not for long-term deep use |
| Acrylic (PMMA) | <500m | Poor, creep risk | Fair | Good light transmission | Very Low | NOT acceptable for 3000m /7000m deep sea service |
Note: Flange dimension, bolt hole layout and O-ring groove can be fully customized to match your housing design.
Integrated Flange Design Advantage
Traditional separate dome + retainer ring may bring leakage risk under cyclic deep-sea pressure. Our one-piece flanged dome is machined from single optical blank. The flange and dome form a monolithic part:
- Built-in O-ring sealing step for direct watertight assembly
- Custom bolt hole pattern according to your drawing
- Reduce parts count, simplify your mechanical assembly
- Stress distribution optimized for high hydrostatic pressure
Customization Options
- Custom dome OD, ID, wall thickness
- Custom flange diameter, bolt hole positions, O-ring groove size
- AR coating for target wavelength band (VIS / NIR)
- 3000m or 7000m pressure rating selection
- Surface tolerance adjustment to match your housing sealing requirement
FEA Simulation & Pressure Validation
For all flanged dome orders, especially 7000m version, finite element analysis will be performed before machining to check stress concentration on flange root. After optical polishing, hydrostatic pressure testing can be arranged and official test document provided.
MOQ & Lead Time
No ready stock. MOQ 5 pcs. Single piece sample available with sample pricing. Lead time: 3–5 weeks for 3000m flanged dome; 4–6 weeks for 7000m flanged dome including FEA simulation, optical fabrication and pressure validation.
How To Order
Send your mechanical drawing with flange dimension, bolt layout and O-ring requirements. Specify working depth, material and coating needs. Our optical engineer will provide DFM feedback and formal quotation within 24 hours.
