Material Selection Guide for 7000m Dome
Select the optimal optical blank to guarantee safety under 700 bar ultra deep seawater pressure.
Sapphire is the primary recommendation for 7000m extreme deep sea. C-axis oriented sapphire delivers the highest compressive strength, long-term stability under 700 bar. Fused Silica is available but needs thicker wall design and pressure simulation. BK7 / acrylic cannot be used 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 material for 7000m ultra-deep dome port |
| JGS1 Fused Silica | 7000m (reinforced wall + FEA validation) | Very Good | Excellent | Superior optical uniformity | Medium-High | Alternative option, requires customized thick wall & pressure simulation |
| BK7 Optical Glass | <3000m | Not sufficient | Good | Visible band transmission | Low | NOT suitable for 7000m deep application |
| Acrylic (PMMA) | <500m | Poor | Fair | Good light transmission | Very Low | Forbidden for 7000m extreme deep sea |
Note: BK7 and acrylic cannot withstand 700 bar pressure. Sapphire C-axis cut is the top recommendation for long-term ultra-deep operation.
FEA Simulation & Pressure Testing
Mandatory FEA simulation before production plus hydrostatic pressure validation for extreme 700bar conditions.
For all 7000m dome orders, finite element pressure simulation is mandatory before production. After polishing, we support hydrostatic pressure testing to validate safety margin for 700 bar deep water condition.
- FEA finite element pressure simulation prior to machining
- Stress analysis for sapphire / fused silica dome geometry
- Precision grinding & optical surface polishing
- Optional hydrostatic pressure test certificate
