Description
Felix Glass manufactures high-precision custom fused silica domes engineered for airborne UAV turrets, aerospace sensors, satellite optical payloads and high-temperature ground optical test systems. Made from ≥99.99% high-purity synthetic fused silica, these spherical optics maintain stable optical performance under rapid thermal cycling, high temperature and radiation exposure. Full in-house optical fabrication, from R&D prototype to serial mass production. We separate Airborne Aero Grade and Space Grade to match your budget and qualification timeline. Standard optical glasses suffer wavefront distortion under large temperature swings, degrade under radiation, and fail long-duration airborne / aerospace service. High-purity fused silica features ultra-low thermal expansion, broad UV-IR transmission and excellent radiation resistance. The spherical dome protects internal optical sensors, stabilizes optical path and preserves imaging precision under aerodynamic heating, cryogenic shock and high radiation environments. Continuous transmission from deep UV through visible to near infrared, suitable for multi-band airborne sensing, satellite observation and high-temperature optical inspection. Hemisphere, hyper-hemisphere, custom wall thickness, spherical radius, flange and sealing grooves. Aerospace-grade AR, anti-radiation and high-temp anti-oxidation coatings available. Base material: ≥99.99% high purity fused silica (synthetic quartz). We split into two grades to avoid over-spec & high cost: Airborne Aero Grade for UAV / ground thermal test; Space Grade for satellite orbital application. Sapphire dome is available as upgrade for high abrasion / particle erosion environments. Custom vacuum coatings can be specified for thermal shock, radiation or high transmission requirements. Your mission environment, temperature range, radiation exposure and target waveband define dome thickness, curvature and coating. Our fused silica domes deliver stable optical performance for airborne UAV turrets, aerospace launch assemblies, satellite payloads and ground high-temperature optical thermal test stations. Optical protective dome for UAV and airborne electro-optical payloads, preserving imaging performance under aerodynamic heating & vibration. Ultra-precision radiation-resistant dome for earth observation satellite optics, qualified for multi-year stable orbital service. Thermal-shock resistant dome for rocket assemblies and ground aerospace thermal simulation optical test stations. Review dome geometry, tolerance, optical zone, temperature / vibration / radiation requirement, identify manufacturing risk before quotation. Raw blank inspection for inclusion, void and scattering to eliminate substrate-related optical failure at early stage. 5-axis CNC forming and curve grinding to reach near-net spherical profile for fused silica dome. Precision curved surface polishing, followed by vacuum deposition of AR, anti-radiation or anti-oxidation functional coatings. Full optical metrology, thermal shock / vibration test as required; clean room handling and shock-resistant packaging for aerospace supply chain. We accept 1-piece prototype sampling and batch serial manufacturing for custom fused silica domes. Submit your CAD drawing, mission environment, target quantity, coating specs, optical tolerance and acceptance criteria. Our optical engineers perform a free DFM manufacturability assessment before issuing formal quotation. Prototype lead time varies by geometry complexity and coating / test requirements. Simple airborne-grade domes have faster turnaround; space-grade custom domes require dedicated engineering review for budget and timeline optimization. Your system requires ultra-low thermal expansion, wide UV-IR transmission, radiation resistance, stable performance across cryogenic and high temperature, with cost control priority. Optical surface faces sand/particle erosion, repeated wiping, high abrasion; you prioritize Mohs9 extreme hardness, even with higher cost and longer lead time. Airborne grade vs space grade change inspection scope, cost and lead time. Specify waveband, thermal cycling, vibration and radiation requirements for coating selection. A fused silica dome is high-precision hemispherical optical component from high-purity fused silica, protecting optical sensors under airborne, high-temperature and aerospace environments. Ultra-low thermal expansion coefficient, good radiation resistance, wide UV to IR transmittance, stable working range -196°C ~ +1200°C. Yes. Custom diameter, wall thickness, spherical radius, hemispherical / hyper-hemisphere profile, flange and sealing groove per your CAD drawings. AR, anti-radiation and anti-oxidation coatings go through thermal cycling, humidity test and adhesion test. We provide test reports upon request. Simple airborne-grade prototype: 3–5 weeks. Space-grade domes with full environmental qualification require longer timeline, we will confirm during DFM review. Interferometer wavefront measurement, spectral transmittance, blank inclusion screening, dimensional inspection; thermal shock / vibration test certificate for qualified orders. Share your project background, fused silica dome CAD drawing, coating requirements, optical tolerances and quantity. Felix Glass optical engineers will evaluate manufacturability, optical performance and environmental risk, and issue formal quotation for your custom fused silica optical dome.
