Briefing
Custom AR sapphire hemispherical dome for ROV, aerospace and defense optical window assemblies with Mohs 9 sapphire option.
Detailed
Felix Glass Co., Limited manufactures drawing-based sapphire hemispherical domes for engineers who need a hard optical cover for ROV camera housings, aerospace sensors, military-grade observation equipment and other protected imaging assemblies. The dome is intended to protect cameras, sensors and optical paths where a flat window may not provide the required viewing geometry or environmental durability. Sapphire is selected when abrasion resistance, chemical stability and long service life are important design factors. AR, AF, AG or wavelength-specific coating options can be matched to the optical band and use environment. Diameter, radius, wall thickness, edge detail and inspection criteria can be reviewed before production. The primary material option is single-crystal sapphire for hard optical protection. BK7 or fused silica optical glass can also be discussed when the project needs a different balance of cost, spectral range or mechanical requirements. Use conditions should define the final geometry and coating. The same dome family can support different optical systems when the drawing, sealing structure and spectral requirements are reviewed together. For underwater camera housings where optical clarity, pressure design, sealing and abrasion resistance need to work together. For airborne optical assemblies where material stability, coating selection and dimensional review are part of the design process. For observation, inspection and monitoring systems exposed to cleaning, dust, outdoor use or repeated handling. Diameter, radius, wall thickness, optical zone and mounting edge are checked before quoting. Sapphire, BK7 or fused silica is selected according to hardness, optical band and environment. Controlled grinding and forming support the required hemispherical or spherical geometry. Optical polishing and AR, AF, AG or IR coating are planned around the application target. Finished domes are checked for dimensions, surface appearance, optical clarity and coating quality. The original product emphasizes trial orders, custom manufacturing and fast engineering communication. In practical purchasing terms, Felix Glass can review one-piece prototype feasibility, small batch orders and repeat production after receiving a drawing and application details. Quotation timing depends on geometry, coating, tolerance, quantity and inspection requirements. The dome faces abrasion, saltwater exposure, repeated cleaning, outdoor service, thermal stress or long-life optical protection requirements. The application needs general optical clarity and a different cost-performance balance without sapphire-level hardness. The optical design needs UV performance, thermal stability or a material profile better matched to the wavelength range. For a custom hemispherical dome, the inspection plan should be tied to how the part will be mounted and used. Surface appearance alone is not enough for an optical housing component. Diameter, radius, wall thickness and edge profile are checked against the drawing. The optical area is reviewed for clarity, visual defects and coating appearance. Packaging is planned to reduce handling risk for polished and coated surfaces. Yes. Diameter, radius, wall thickness, edge detail and optical zone can be reviewed from your drawing. No. Transmission depends on wavelength range, coating design, substrate thickness and inspection method. Share the optical band for review. Sapphire is commonly considered for underwater optical covers because it offers hardness, corrosion resistance and stable protection when the housing design is appropriate. Please provide drawing, material, diameter, radius, wall thickness, coating, quantity, application environment and inspection requirements. Share your application, optical band, drawing, coating target, quantity and inspection requirements. Felix Glass can review manufacturability and prepare a quotation path for your AR sapphire hemispherical dome project.
