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 ROV camera dome available in sapphire, fused silica and BK7 with custom coating and sealing interface. Sapphire is premium for deep‑sea long‑term deployment; fused silica and BK7 fit medium‑shallow depth budget projects. Deliver reliable optical dome solutions matched to your subsea operating conditions. 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. Sapphire dome supports up to 10 000 m full‑ocean depth. Fused Silica and BK7 maximum depth are constrained by material mechanical performance. Mohs‑9 sapphire resists seabed sediment scouring. Fused silica and BK7 have lower hardness for low‑sediment underwater environments. Above 96 % visible‑light transmittance. Single‑sided or double‑sided anti‑reflection coating for visible, UV or IR spectrum requirements. Custom diameter, wall thickness, radius and sealing flange geometry to fit your existing ROV / AUV mechanical assembly. Minimal optical distortion under ocean temperature fluctuation for continuous underwater observation tasks. Reference parameters for custom‑made ROV and subsea camera dome. Complete in‑house production workflow for marine‑grade optical dome quality assurance. Custom‑manufactured underwater optical domes for global marine engineering customers. Specialized precision optical component manufacturer Delivered multiple subsea optical projects Support low‑volume sample and mass production orders Dimensional and optical performance testing Material, dimension and coating fully customizable A: Yes. We customize dome radius, diameter, wall thickness and sealing flange geometry based on your CAD files or technical specifications. 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. A: Sample order: 8‑14 working days. Mass‑production order: 18‑25 working days, subject to drawing complexity. A: Yes, single‑sided and double‑sided broadband AR coatings are available for visible, UV and infrared spectrum requirements. 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. Please provide working depth, spectral requirement, dimension drawing or specifications. Our optical engineer will send detailed quotation for you within 24 hours.
