Home / Custom Fused Silica Optical Dome Manufacturer
Precision fused silica and fused quartz optical domes for UV, visible, NIR, laser, imaging and high-temperature optical systems—made to your geometry, wavelength, optical surface and mounting requirements. Dongguan Felix Glass Co., Ltd. coordinates material evaluation, precision forming, grinding, optical polishing, AR / BBAR coating and final dimensional and optical inspection for prototype, validation and repeat production projects. Factory-direct custom manufacturing•UV / Visible / NIR engineering•Prototype to production A dome is a curved optical interface. Material, geometry, optical surface, coating and mounting must be evaluated together. Diameter, radius, thickness, concentricity, clear aperture and mounting geometry must work together. Optical-path surfaces require controlled grinding, polishing, surface quality and inspection—not cosmetic finishing. Low thermal expansion helps, but the dome must still be assessed with its mount, coating and operating environment. UV, visible, NIR and broadband systems can require different coating bands and incidence considerations. Approved geometry, optical surface, coating and inspection requirements must transfer into repeat batches. No finished drawing yet? Start with diameter, thickness, radius, wavelength, application, quantity, a CAD file, photo or reference sample. Major processing stages are reviewed as one system, from optical material to finished dome. Review wavelength, transmission, temperature, thermal cycling, geometry, thickness and application. Spherical, hemispherical and custom curved profiles with drawing-defined clear apertures and interfaces. Cutting, precision forming or CNC, grinding, optical polishing and inspection selected for the specification. UV AR, AR, BBAR, broadband, compatible NIR and application-specific surface treatments. Critical dimensions, dome geometry, optical surface, appearance, coating and customer-defined criteria. Single engineering prototypes for suitable projects, validation batches and controlled repeat production. These categories define the project specification; they are not a physical layer stack. Fused silica / fused quartz selected for wavelength, transmission, temperature and optical quality. UV / visible / NIR range, transmission target, clear aperture, surface figure and optical path. Cutting, CNC, forming, profile generation, grinding, edges, chamfers and optical polishing. UV AR, wavelength-specific AR, BBAR, broadband, compatible NIR and environmental treatments. Material, dimensional, optical surface, coating, appearance and final quality control. Final material grade, geometry, coating and inspection plan are confirmed against the approved drawing and application requirements. Final values are application- and drawing-dependent. The table defines the information available for customization without inventing universal tolerances. Real product images supplied for this project, presented separately from manufacturing and application information. Custom diameter, radius, wall thickness and optical surface requirements. Custom flange and mounting-interface geometry for system integration. Drawing-based curved optical components for OEM assemblies. Spherical, hemispherical and application-specific curved profiles. Engineering samples and repeat production against approved specifications. The following are application categories supported by engineering review. They are intentionally presented without unrelated stock imagery. UV cameras, UV imaging, UV sensors, spectroscopy and scientific optical equipment. Industrial cameras, optical sensors, specialized imaging and automated inspection systems. Compatible laser systems, photonics equipment, optical measurement and scientific assemblies. Furnace cameras, industrial process monitoring, optical sensors and thermal environments. Airborne imaging, UAV optical systems, navigation sensors and external optical protection. Application suitability depends on the selected fused silica grade, wavelength, geometry, thickness, coating, mounting design and operating environment. A coordinated route from raw material preparation and dome generation through optical finishing, coating and inspection. Start with a drawing, preliminary dimensions or reference sample; the specification is refined before production. Material, geometry, wavelength, surface, coating, mounting and quantity. Suitable projects may begin with a 1-piece engineering sample. Evaluate geometry, dimensions, surface, coating, mounting and integration. Confirm manufacturing consistency before larger production. Repeat manufacturing against the approved specification and quality route. Fused silica is considered where optical transmission, thermal stability and precision optical finishing must work together. Applicable steps and inspection criteria are selected according to material, dome geometry, optical requirements, coating and application. Verify substrate against incoming requirements and defined criteria. Prepare blanks to approved dimensions and manufacturing requirements. Machine contours, diameter, thickness, interfaces and custom geometry. Control geometry, edge condition and surface preparation. Finish optical surfaces to defined project requirements. Apply specified AR, BBAR, IR or functional surface treatment. Inspect critical dimensions, geometry, surfaces and coating. Verify, protectively package and release approved products. A curved optical component made from fused silica and used as a protective or functional optical interface for imaging, sensing, laser, scientific and specialized systems. It offers a different combination of optical and thermal characteristics, including very low thermal expansion and suitability for many UV applications. Selection still depends on wavelength, temperature and system requirements. It is widely used for UV applications. The usable wavelength and performance depend on material specification, thickness, surface condition and coating. Yes. Hemispherical, spherical and custom curved geometries can be evaluated against radius, diameter, thickness, aperture and mounting requirements. Yes. Submit a 2D drawing, CAD file, preliminary dimensions or reference sample for engineering review. Yes. UV AR solutions can be evaluated according to wavelength, substrate, incidence conditions and environment. Yes, for suitable configurations. Provide wavelength, power or energy conditions, surface-quality and coating requirements for evaluation. Temperature change can affect both the dome and its mounting relationship. Fused silica’s low thermal expansion can help where thermal dimensional stability matters. Yes. Edges, shoulders, locating features and other integration dimensions can be evaluated from the drawing. Suitable projects may start from 1 piece, subject to engineering review. No. Preliminary dimensions, wavelength, application information or a reference sample can begin the review. Send material preference, diameter, thickness, radius, wavelength, coating, quantity, application and a drawing when available. Suitable configurations may require approximately 3–5 working days. Final timing depends on material, geometry, polishing, coating and inspection. Yes. Pilot and small-batch production can be arranged after prototype validation. Yes. Approved configurations can transfer into repeat production under the defined manufacturing and inspection route. Inspection and quality documentation can be discussed and supplied according to agreed project requirements. Yes. Drawing-based custom manufacturing and project-defined inspection criteria are supported. Yes. Share wavelength, temperature, application, geometry and optical requirements so the engineering team can evaluate fused silica or another material. A complete drawing is not required. Send the information you have and our team can identify the key material, geometry, optical, coating and inspection requirements.
