Material Selection Guide for 3000m Dome
Select the optimal optical blank to avoid failure under 300 bar deep seawater pressure.
Fused Silica (JGS1) is the preferred option for 3000m deep sea. It offers high compressive strength, stable optical transmission and strong resistance to seawater corrosion. BK7 is available for cost-sensitive projects with strict annealing process. Acrylic is NOT acceptable for 3000m service.
Material Selection Chart
| Material | Max Rated Depth | Hydrostatic Resistance | Seawater Resistance | Optical Performance | Cost Level | Recommended Use Case |
|---|---|---|---|---|---|---|
| JGS1 Fused Silica | 3000m+ | Excellent | Excellent | High transmittance, low birefringence | Medium | Primary choice for 3000m ROV/AUV camera dome |
| BK7 Optical Glass | ≤3000m (with strict annealing) | Good | Good | Good for visible band | Low | Cost-sensitive projects, not for long-term deep immersion |
| Sapphire | 7000m+ | Outstanding | Outstanding | High hardness & transmission | High | Reserve upgrade option for 3000m when extra safety margin needed |
| Acrylic (PMMA) | <500m | Poor, creep risk | Fair | Good light transmission | Very Low | NOT acceptable for 3000m service |
Note: Acrylic is not recommended for 3000m deep water due to material creep and failure risk under high pressure.
Manufacturing & Pressure Validation
Rigorous machining workflow and pressure simulation to guarantee subsea reliability.
Every custom dome port is precision ground, polished and inspected. We perform pressure simulation before machining. Final hydrostatic pressure test can be provided upon request to verify safety margin under 300 bar.
Customization Options
Custom geometry, coating and tolerances matched to your underwater camera housing design.
- Custom OD, ID, wall thickness & flange dimension
- AR coating for target wavelength band
- Custom drawing tolerance per your mechanical housing
- Flat optical window alternative if you do not need wide-angle dome
MOQ & Lead Time
All 3000m optical dome ports are custom manufactured with no ready stock.
No ready stock. MOQ is 5 pcs. Sample order of 1 piece is supported with separate sample cost. Production lead time 3–5 weeks including inspection and pressure test.
