Core Pain Points We Solve
Ordinary optical domes corrode quickly under long-term marine salt fog & seawater splash
Conventional coating fails in high humidity marine environment, causing fogging & light loss
Sea sand & marine sediment scratch dome surface during offshore vessel operation
Few suppliers supply integrated AR+anti-fog coating customized for marine surveillance
Product Key Advantages
Superior Salt Fog Corrosion Resistance
Single crystal sapphire substrate with inert chemical property, withstand long-term offshore salt spray environment without oxidation & corrosion.
Dual AR+AF Marine Special Coating
Custom anti-reflection & anti-fog composite coating, eliminate seawater fogging, maintain stable light transmittance in high humidity coastal areas.
High Hardness Anti-Scratch Surface
Mohs 9 sapphire material resists sea sand, floating debris abrasion during ship & offshore platform operation.
Wide Spectrum Surveillance Compatibility

Frequently Asked Questions
Q1: How long can the sapphire dome resist marine salt fog erosion?
A: High purity single crystal sapphire is chemically inert, combined with our special marine coating, it can work stably for years under continuous coastal salt fog environment without corrosion.
Q2: What is AR+AF composite marine coating function?
A: AR layer improves light transmittance, AF anti-fog layer prevents seawater mist condensation on dome surface, guarantee clear imaging in humid sea weather.
Q3: Is plastic dome a substitute for marine sapphire dome?
A: Plastic will age, scratch and corrode quickly under sea salt & UV; sapphire is the only long-term reliable option for professional marine surveillance equipment.
Q4: Can you customize special sealing edge for marine camera housing?
A: Yes, we support customized chamfer, step edge structure to match waterproof marine camera shell sealing design.
Q5: Do you provide marine dome performance test report?
A: We can provide salt fog aging test, optical transmittance and anti-fog test official reports for your equipment certification.
