Material Selection Guide

High-Purity Fused Silica

Best for: All aerospace, satellite, and high-end optical applications.

Advantages: Ultra-low thermal expansion, high transmission (UV to IR), excellent radiation and high-temperature resistance.

Manufacturing Capability

All domes are fully produced in-house with a closed-loop process:

CNC Cutting → Precision Grinding → Ultra-fine Polishing → Vacuum Coating → Full Optical Inspection

Strict process consistency guarantees the high stability and reliability required for aerospace and defense systems.

Application Solutions (Problem & Solution)

Aerospace Sensor Protection

Problem: Harsh environmental factors (dust, impact, temperature) degrade sensor performance.

Solution: Our robust optical protection dome provides a hermetic, clear barrier, ensuring sensor integrity.

Satellite Optical Payload

Problem: Long-term space radiation causes optical attenuation and performance drift.

Solution: Our radiation resistant dome maintains high transmittance and stability for years in orbit.

Rocket & High-Temperature Systems

Problem: Extreme heat and thermal shock damage optical components.

Solution: Our high temperature window dome withstands rapid temperature changes and maintains its shape and clarity.

Scientific Research & Deep Space

Problem: Need for ultimate precision and stability in unexplored environments.

Solution: Our ultra-precise, custom-engineered domes meet the most stringent scientific requirements.

Project Cases

European Satellite Constellation Project

Custom satellite optical domes with anti-radiation coating, successfully integrated into a new Earth observation satellite constellation, providing clear, distortion-free imagery for 5+ years.

US Aerospace Defense Project

High-temperature window domes for advanced missile defense systems, withstanding extreme thermal stress and maintaining critical optical performance during flight.

Quality Control & Testing Equipment

We rely on professional precision testing instruments to ensure every dome meets aerospace-grade standards:

- Laser Interferometer: Verifies optical flatness and surface uniformity.

- Spectrophotometer: Tests full-band transmittance and coating performance.

- Coordinate Measuring Machine (CMM): Calibrates complex 3D geometries and tolerances.

- Radiation Test Chamber: Simulates space radiation to validate long-term stability.

- Thermal Shock Tester: Validates performance under extreme temperature fluctuations.

100% full-item inspection before shipment. Third-party test reports (e.g., SGS, BV) are available for high-end OEM projects.
