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 ghost image and flare
  • Custom coating for target spectrum: visible light, near infrared or multi-band

Important notes for subsea AR coating

You must specify your working wavelength range before coating. Wrong wavelength coating will not deliver expected optical performance. AR coating is optional for dome ports, not standard default.

AR coating is available on both JGS1 fused silica and C-axis sapphire dome substrates.

FAQ

Q: Is AR coating standard included on your domes?
A: No, AR coating is an optional add-on service.

Q: Can AR coating work for both visible and infrared?
A: Yes, multi-band broadband AR coating can cover combined spectrum.

Q: Does seawater damage AR coating?
A: Our marine-grade AR coating has good seawater resistance for subsea service.

Q: Can we add AR coating on flanged optical dome?
A: Yes, integrated flanged dome supports AR coating.
