FELIX GLASS SUBSEA DOME FAQStandard Dome vs Integrated Flanged Dome PortTwo major dome mechanical designs for subsea imaging systems: standalone standard dome and monolithic integrated flanged dome port. The core difference is assembly method and sealing interface count.Standard standalone dome portStandard hemispherical dome requires separate retainer ring to clamp it onto housing. It works well ...

FELIX GLASS SUBSEA DOME FAQHydrostatic Pressure Test for Subsea Dome PortHydrostatic pressure test is physical pressure testing to verify the optical dome can withstand its rated water depth pressure before deployment. It is an optional validation step after optical polishing.How hydrostatic test worksThe dome sample is placed inside pressure chamber, pressurized to target pressure (300 bar for 30...

What is AR coating on subsea optical dome port?AR coating, or anti-reflection coating, is a thin multi-layer optical film deposited on dome surfaces. It reduces light reflection loss and boosts light transmission for subsea cameras, LiDAR and optical sensors.Key benefits of AR coating for underwater dome Higher optical transmission, brighter image for low-light deep sea environment Reduce ...

What is FEA simulation for subsea dome port?FEA (Finite Element Analysis) simulation is a computer-based stress simulation to predict stress distribution, peak pressure load and crack risk on optical dome ports under deep-sea hydrostatic pressure.Why run FEA for subsea dome port?Underwater dome failure usually occurs at stress hotspots, especially the dome root, or the transition area between hemi...

What material is best for subsea optical dome port?Selecting the right substrate is critical for subsea dome port performance, pressure resistance and service life. The three common optical materials are C-axis Sapphire, JGS1 Fused Silica and BK7 optical glass. Acrylic is not recommended for deep-water pressure applications.C-axis SapphireSapphire is the top choice for 7000m abyssal deployment. It...
