Detail Information
Felix Glass Co., Limited manufactures custom sapphire optical dome components for engineers who need a hard, clear and chemically stable protective cover for cameras, sensors, ROV equipment, aerospace assemblies and industrial optical systems. A sapphire optical dome is selected when a flat window or standard glass cover does not provide enough scratch resistance, pressure durability, heat stability or optical protection. The dome shape helps protect the optical path while supporting wide-angle viewing or compact sensor enclosure designs. Polishing and optional AR coating are matched to the required visible, NIR or selected IR use case. Diameter, radius, wall thickness, edge detail, coating and inspection criteria can be reviewed before production. The standard material is synthetic single-crystal sapphire, also known as Al2O3 corundum. BK7 or K9 optical glass can be discussed as a secondary custom option when the project does not require sapphire hardness. Use conditions should define the final dome size, coating and inspection standard. The same material family can serve different environments when the geometry and coating are specified correctly. For subsea imaging, pressure, corrosion, sealing and optical clarity must be considered together. For airborne or defense-related equipment, drawings often define material, coating and inspection requirements. For inspection cameras and monitoring systems, sapphire helps protect exposed optics from abrasion and cleaning. 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. The original listing supports small custom orders and larger-volume production. For a practical quotation, send your dome drawing, target quantity, material requirement, coating request, tolerance, surface quality, working environment and any inspection standard. Sample timing and bulk delivery depend on geometry, coating and inspection requirements. For simple projects, Felix Glass can review feasibility quickly; for complex optical assemblies, engineering discussion helps avoid overbuilding the part. 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. The part can be reviewed by drawing for diameter, spherical radius, wall thickness, edge detail and optical zone. No. Transmission depends on wavelength range, coating design, material thickness and inspection method. Share the optical band for review. Sapphire is often selected for underwater optical covers because it offers hardness, corrosion resistance and stable optical protection when the housing design is correct. Please provide drawing, material, size, radius, thickness, coating, quantity, application environment and inspection requirements. Share the application, drawing, coating target and quantity. Felix Glass can review manufacturability, inspection points and quotation details for your custom sapphire optical dome project.
