Direct answer

Optical System Risks Solved By Fused Silica Dome

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.

99.99% High-Purity Fused Silica Substrate

Premium SiO₂ blank with minimal inclusion & scattering. Ultra-low CTE, stable performance across cryogenic up to +1200°C for airborne and aerospace optical missions.

Broad Spectrum UV-VIS-IR Transmission

Continuous transmission from deep UV through visible to near infrared, suitable for multi-band airborne sensing, satellite observation and high-temperature optical inspection.

Full Custom Geometry Per CAD Drawing

Hemisphere, hyper-hemisphere, custom wall thickness, spherical radius, flange and sealing grooves. Aerospace-grade AR, anti-radiation and high-temp anti-oxidation coatings available.

Original capability retained

From Single Prototype To Batch Fused Silica Dome Orders

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.

Decision support

Select Fused Silica vs Sapphire Dome For Your Project

Choose Fused Silica Dome When

Your system requires ultra-low thermal expansion, wide UV-IR transmission, radiation resistance, stable performance across cryogenic and high temperature, with cost control priority.

Upgrade To Sapphire Dome When

Optical surface faces sand/particle erosion, repeated wiping, high abrasion; you prioritize Mohs9 extreme hardness, even with higher cost and longer lead time.

Define Coating & Grade Early

Airborne grade vs space grade change inspection scope, cost and lead time. Specify waveband, thermal cycling, vibration and radiation requirements for coating selection.
