Detail Information
Felix Glass Co., Limited manufactures high-precision, high-stability custom fused silica domes built for aerospace sensors, satellite optical payloads and extreme environment optical systems. Fabricated from ≥99.99% high-purity fused silica, our aerospace-grade spherical optics deliver reliable optical protection under extreme temperature, cosmic radiation and harsh space operating conditions. We maintain full in-house production capacity, supporting engineering prototype development through mass-volume serial manufacturing. Conventional optical glass cannot survive extreme temperature swings, continuous cosmic radiation and long-duration orbital service required by aerospace equipment. High-purity fused silica dome features ultra-low thermal expansion, wide-spectrum light transmission and superior radiation resistance. The spherical dome structure shields internal optical sensors, stabilizes optical path performance and maintains imaging precision under complex outer space and aerodynamic environments. Stable transmittance covering UV, visible and infrared wavebands, supporting satellite observation, aerospace sensing and scientific optical detection systems. Hemisphere, hyper-hemisphere, wall thickness, curvature and aerospace specialized coating schemes are customizable strictly per customer engineering drawings. The baseline material is ≥99.99% high purity fused silica (quartz). For applications requiring extreme surface hardness, we provide sapphire dome as an alternative upgrade solution. We support multiple customized optical coatings to satisfy space radiation resistance, high-temperature anti-oxidation and high-transmission requirements. Orbital altitude, temperature range, radiation exposure and target optical waveband determine final dome thickness, curvature and coating configuration. Our fused silica domes maintain long-term stable optical performance for aviation, space launch, satellite payload and ground high-temperature optical testing equipment. Optical protection dome for aircraft and unmanned aerial vehicle sensing systems to guarantee stable signal transmission during flight. Ultra-precision radiation-resistant dome for earth observation satellite optical systems, designed for multi-year stable orbital operation. Dome-shaped high-temperature optical window resisting thermal shock for rocket assemblies and ground aerospace thermal simulation testing stations. Verify dome diameter, curvature, wall thickness, optical zone, tolerance, temperature and radiation service specifications. Select qualified fused silica ingot and calculate machining allowance based on aerospace geometry standards. Controlled CNC forming and curve grinding to achieve near-net shape of spherical aerospace dome. Ultra-precision optical polishing followed by vacuum deposition of AR, anti-radiation or anti-oxidation functional coatings. Full optical, dimension and environmental simulation testing; vibration-proof transit packaging for aerospace supply chain. We support single-unit prototype sampling and large-scale batch manufacturing of custom aerospace fused silica domes. To obtain accurate formal quotation, please submit engineering drawing, target quantity, geometry specification, coating requirements, optical tolerance, extreme operating environment and aerospace inspection acceptance criteria. Prototype lead time and bulk delivery cycle depend on dome geometry complexity, specialized aerospace coating and testing requirements. Conventional fused silica dome designs complete feasibility assessment rapidly; complex space-grade customized domes will schedule dedicated engineering communication to optimize structure and control overall project budget. System requires ultra-low thermal expansion, wide UV-IR transmission, radiation resistance and stable performance under extreme high / cryogenic temperatures. The optical surface faces persistent abrasion, repeated cleaning, high-speed particle erosion, prioritizing Mohs 9 extreme surface hardness. The mission operates in outer space with cosmic radiation, high-temperature oxidation, or requires controlled reflectivity across specific optical wavebands. A fused silica dome is a high-precision hemispherical optical component manufactured from high-purity fused silica, designed to protect optical sensors working under extreme aerospace and high-temperature environments. Fused silica delivers ultra-low thermal expansion coefficient, outstanding radiation resistance, wide-spectrum UV to IR transmittance, and stable performance from cryogenic up to 1200°C. Yes. We customize diameter, wall thickness, spherical radius, hemispherical / hyper-hemispherical profile and special structural features strictly according to customer engineering drawings. We supply wavelength-specific AR anti-reflection coatings, space-grade anti-radiation coating and high-temperature anti-oxidation multilayer vacuum coatings. Yes, we accept MOQ of 1 piece for engineering prototype testing, supporting aerospace pre-qualification and verification projects. Share your aerospace project background, fused silica dome engineering drawing, coating specifications and target order quantity. Felix Glass optical engineering team will evaluate manufacturability, optical performance, environmental test requirements and issue official quotation for custom aerospace fused silica optical dome.
