Engineering Challenges & Targeted Solutions
Challenge 1: Low optical clarity and severe image distortion under seawater
Solution: Adopt high-purity high-transmittance BK7 optical glass substrate with ultra-precision spherical polishing, effectively reduce light refraction distortion and maintain stable clear underwater imaging.
Challenge 2: Water leakage risk under deep-sea high pressure
Solution: Reinforced thick-wall pressure-resistant dome structure matched with precision chamfered sealing edge, realizes tight seamless assembly with camera housing for long-term waterproof performance.
Challenge 3: Internal lens fogging and surface degradation under humid marine environment
Solution: Optional anti-fog coating and hard anti-scratch protective coating, prevents internal fogging and seawater surface corrosion to extend dome service life.

FAQ
1. What material is standard for deep-sea underwater optical dome?
BK7 optical glass is our standard substrate; fused silica or quartz can be selected as alternative material for high-temperature, ultra-deep high-pressure marine working conditions.
2. Can we customize coating to prevent lens fogging under water?
Yes, we provide optional anti-fog coating matched with AR anti-reflective coating, which effectively eliminates internal fogging caused by seawater temperature difference.
3. Is prototype testing available with low minimum order quantity?
We support MOQ as low as 1 piece for prototype performance testing, no large batch order restriction for early-stage equipment R&D verification.
4. Does every underwater dome get full inspection before shipment?
Yes, each finished dome will complete dimensional tolerance check, surface defect screening, transmittance testing and waterproof compatibility testing under our ISO9001 quality inspection system.
