Detail Information
Felix Glass manufactures precision custom single crystal sapphire domes for harsh-environment optical protection. We fabricate hemispherical / spherical sapphire domes for underwater ROV cameras, aerospace EO/IR sensors, airborne optics and industrial machine vision. Achieve scratch-dig down to 10/5, λ/10 surface flatness, customized radius, wall thickness and AR/NIR/IR coatings. 1pc prototype available | COA inspection report | NDA acceptable Select sapphire dome when flat optical windows or standard glass cannot withstand deep-sea pressure, sand abrasion, salt fog corrosion, thermal shock or long-term outdoor exposure. Dome geometry maintains wide-angle optical path while protecting imaging sensors in sealed camera housings. Ultra-precision polishing + custom AR coating optimized for UV, VIS, NIR or mid-IR wavelength bands. Custom dome diameter, spherical radius, wall thickness, flange, edge chamfer, scratch-dig & flatness tolerance. Base material: synthetic single-crystal sapphire (Al₂O₃). BK7/K9 optical glass alternative available for non-extreme environment projects to reduce cost. Final dome geometry, coating and inspection standard are defined by working depth, pressure, wavelength and environment. Our sapphire domes maintain optical performance under harsh underwater, airborne and high-temperature conditions. Deep sea high-pressure optical cover, resistant to seawater corrosion and sand erosion, keeps imaging clarity in long subsea missions. Airborne optical domes for electro-optical infrared systems, stable under vibration and wide temperature variation, NDA & COA available. Protective dome for outdoor inspection cameras, withstand frequent cleaning and particle abrasion, reduce field maintenance cost. Diameter, radius, wall thickness, flange or edge form, optical zone and mounting method are checked. Sapphire blank size, machining allowance and coating route are planned according to the application. Diamond tooling and controlled polishing are used to form the dome and improve optical clarity. AR, AF, AG or other coatings are selected by wavelength range, cleaning method and service environment. Finished parts are checked for dimensions, surface quality, coating appearance and shipment protection. We accept low-volume prototype and large batch OEM orders. To get fast, accurate quotation, send your dome 2D/3D drawing, target quantity, material selection, coating wavelength, tolerance, scratch-dig requirement, working pressure/environment and inspection standards. Sample and bulk lead time depends on geometry complexity, coating and inspection criteria. Our optical engineers review manufacturability before quotation to avoid unexpected production risk. The cover faces abrasion, repeated cleaning, salt fog, heat, pressure, outdoor exposure or long-service optical protection requirements. The part needs optical clarity but does not require sapphire hardness or severe environment resistance. The optical system has a defined wavelength band, reflection target, fingerprint exposure or glare concern. Yes. We manufacture per your 2D/3D drawing, custom outer diameter, spherical radius, wall thickness, flange geometry and optical zone. Scratch-dig from 60/40 down to 10/5. Surface flatness λ/10 is available for high precision EO/IR optical systems. Yes. COA with dimension and optical test data provided per batch. NDA agreement is available for aerospace and defense EO/IR projects. Yes, 1pc prototype is acceptable. Sample lead time:7~14 working days. Mass production lead time: 20~35 working days. Sapphire is ideal for subsea camera housings. High mechanical strength, seawater corrosion resistance. We evaluate pressure requirement during drawing review. Submit your 2D/3D drawing, target quantity, wavelength/coating spec, working pressure, scratch-dig requirement and inspection criteria. Share your optical requirement, 2D/3D drawing, coating target, working pressure and quantity. Felix Glass optical engineers will evaluate manufacturability, estimate lead time and provide formal quotation for your custom sapphire dome project.
