Custom Sapphire Underwater Optical Dome for Marine Camera Protection
This sapphire underwater optical dome is built for marine cameras, ROV vision modules, offshore monitoring equipment, and optical systems that need a hard protective cover without sacrificing image clarity. Single-crystal sapphire gives the dome Mohs 9 surface hardness, strong scratch resistance, stable optical transmission, and reliable performance in wet, high-pressure environments.
A Scratch Resistant Answer to Underwater Image Distortion
Ordinary protective glass can reduce transmission, introduce distortion, and wear quickly when exposed to sand, saltwater, cleaning cycles, or mechanical contact. This custom sapphire optical dome is designed to protect the camera window while helping the imaging path stay clear, stable, and repeatable. For projects that require a different budget or optical material, BK7 and K9 optical glass can also be reviewed as secondary custom options.
Low Distortion Imaging
Precision shaping and polishing help control aberration so the dome can support underwater observation, machine vision, and sensor protection.
Waterproof Optical Protection
The dome geometry and material stability make it suitable for camera housings, marine optical covers, and sealed optical assemblies.
Why Sapphire Fits Marine Optical Protection
Sapphire is selected when the dome must combine optical clarity with mechanical durability. It can support visible, UV, and IR related optical designs depending on coating and project requirements, while its high hardness helps reduce surface damage that could scatter light or blur captured images.
- Custom diameters from 1 mm to 150 mm based on drawings and housing design.
- AR, IR, UV, and AF coating options for different spectral and cleaning requirements.
- High transmittance and low distortion for underwater camera and sensor systems.
- OEM support for marine cameras, medical devices, laser systems, and industrial optics.

Drawing Review
Felix Glass reviews dome diameter, height, thickness, tolerance, coating, working medium, and optical path before quotation.
Material and Forming
Sapphire material is selected and processed according to project requirements, with optical glass options available for alternative designs.
Precision Polishing
Polishing focuses on optical surface quality, controlled distortion, and the fit needed for camera or sensor housings.
Inspection and Packing
Each dome is checked for dimensional accuracy, appearance, coating requirement, and order documentation before shipment.
Coating, Size, and Drawing Based Customization
Projects can request AR coating to improve light transmission, IR or UV coating for wavelength related applications, and AF coating to reduce fingerprint or cleaning issues. For housing integration, Felix Glass can discuss custom outside diameter, dome height, wall thickness, edge design, and assembly fit based on your drawing or sample.
For fast evaluation, share the optical drawing, target wavelength, pressure or sealing condition, quantity, and inspection requirements.

FAQ for Sapphire Underwater Optical Domes
Can the dome size be customized for a camera housing?
Yes. Diameter, dome height, wall thickness, edge detail, and coating can be reviewed from your drawing, sample, or housing requirement.
Why choose sapphire instead of common optical glass?
Sapphire is much harder and more scratch resistant than common optical glass, making it useful for exposed marine, industrial, aerospace, and protective optical covers.
Can coatings be added?
Yes. AR, IR, UV, and AF coating options can be discussed according to wavelength range, transmission target, cleaning method, and operating environment.
