FELIX GLASS SUBSEA DOME FAQ
Can subsea optical dome port be repaired after scratch?
Minor surface scratches affect optical performance and may create coating failure points. Repair feasibility depends on scratch depth, substrate material and optical tolerance requirements.
Scratch repair rules
- Very shallow surface scratches: can be re-polished, but material removal will alter dome radius and dimensional tolerance.
- Deep scratches, cracks or chips: cannot be repaired; dome replacement required.
- AR coating damage: full recoating is possible only after surface refinishing.
Material difference
Sapphire is harder and more scratch resistant than fused silica. But once deep scratches form on sapphire, re-polishing takes longer and costs more.
Important Warning
Re-polishing changes wall thickness. If the dome is pressure-rated for deep sea, rework may reduce safety factor and invalidate FEA / hydrostatic test certification.
FAQ
Q: Can deep scratches on sapphire dome be fixed?
A: Deep scratches or cracks cannot be repaired, replacement is needed.
Q: Will re-polishing affect pressure rating?
A: Yes, material removal reduces wall thickness, may lower safety factor and void certification.
Q: Can I re-coat only the damaged area?
A: No, AR coating needs full surface stripping and re-deposition for uniform performance.
