Core Pain Points For Subsea Optical Dome Deployment

Poor dome performance leads to scratch, rupture or image degradation in harsh marine environments.

Seawater corrosion shortens service life

Hydrostatic pressure causes dome rupture at depth

Seabed sediment abrasion scratches optical surface

Low transmittance blurs underwater imaging quality

Custom Underwater Optical Dome & Subsea Dome Lens

ROV camera dome available in sapphire, fused silica and BK7 with custom coating and sealing interface.

Material Selection for Underwater & Subsea Optical Dome

Sapphire is premium for deep‑sea long‑term deployment; fused silica and BK7 fit medium‑shallow depth budget projects.

Material	Working Depth Range	Core Strength	Main Limitation	Typical Application
Sapphire	0‑10000 m Full‑ocean depth	Mohs 9 hardness, anti‑abrasion, seawater inert, long service life	Higher cost for large‑size parts	Work‑class ROV, AUV, offshore subsea station
Fused Silica	0‑1500 m Medium depth	Excellent UV transmittance, no birefringence, moderate cost	Low abrasion resistance, avoid deep‑sea heavy sediment	Shallow‑medium ROV, underwater UV spectral detection
BK7 Optical Glass	0‑300 m Shallow‑water only	Low cost, excellent visible‑light imaging performance	Poor seawater resistance, not for UV, forbidden for deep dive	Near‑shore prototype, short‑term underwater camera system

Key Advantages of Our Custom Subsea Optical Dome

Deliver reliable optical dome solutions matched to your subsea operating conditions.

Marine‑Grade Seawater & Salt‑fog Resistance

Sapphire is chemically inert for long‑term deep‑subsea deployment. Fused silica and BK7 are available for shallow‑to‑medium depth budget‑oriented underwater missions.

Custom Hydrostatic Pressure Resistance

Sapphire dome supports up to 10 000 m full‑ocean depth. Fused Silica and BK7 maximum depth are constrained by material mechanical performance.

Abrasion‑Resistant Optical Surface

Mohs‑9 sapphire resists seabed sediment scouring. Fused silica and BK7 have lower hardness for low‑sediment underwater environments.

High Transmittance With Custom AR‑Coating

Above 96 % visible‑light transmittance. Single‑sided or double‑sided anti‑reflection coating for visible, UV or IR spectrum requirements.

CNC Precision Custom Machining

Custom diameter, wall thickness, radius and sealing flange geometry to fit your existing ROV / AUV mechanical assembly.

Stable Optical Performance Under Wide Temperature

Minimal optical distortion under ocean temperature fluctuation for continuous underwater observation tasks.

FAQ | Custom Underwater Optical Dome for ROV & Subsea

Q1: Can you produce ROV optical dome according to customer CAD drawings?

A: Yes. We customize dome radius, diameter, wall thickness and sealing flange geometry based on your CAD files or technical specifications.

Q2: Is sapphire dome suitable for long‑term seawater immersion?

A: Sapphire is premium option for deep‑sea and long‑term deployment. Fused silica and BK7 are also viable for shallow‑medium depth underwater missions with pressure and abrasion constraints.

Q3: What is typical lead‑time for custom subsea optical dome?

A: Sample order: 8‑14 working days. Mass‑production order: 18‑25 working days, subject to drawing complexity.

Q4: Do you provide anti‑reflection AR coating service?

A: Yes, single‑sided and double‑sided broadband AR coatings are available for visible, UV and infrared spectrum requirements.

Q5: Can I select Fused Silica or BK7 instead of sapphire for ROV optical dome?

A: Yes. Fused silica fits medium‑depth projects with UV optical requirements. BK7 delivers cost‑effective solution for shallow‑water short‑term underwater systems. Our optical engineer will recommend proper material according to your working depth, spectral requirement and project budget.
