Hemispherical Quartz Domes

Hemispherical Quartz Domes

-- Steady & Reliable Manufacturer --

Introduction

Our hemispherical quartz domes are precision-engineered optical and protective covers characterized by their excellent transparency across the UV to IR spectrum and their remarkable thermal endurance. Used predominantly in aerospace, high-end surveillance systems, and high-temperature imaging, these domes provide an unparalleled view port while protecting sensitive internal components from extreme heat, pressure, and chemical exposure. Manufacturing involves precise grinding and polishing to ensure minimal optical distortion.

Specification Parameters

ParameterDetails
Material PurityOptical Grade Fused Silica
Diameter Range20 mm to 300 mm
Wall Thickness UniformityGuaranteed flatness/parallelism ≤10 arc seconds

Applications

  • Missile and Aircraft Systems: Used as protective radomes/windows for sensors and cameras operating at high speeds.

  • Underwater ROV/Sonar: Provides a robust, highly transparent cover for deep-sea imaging equipment.

  • High-Temperature Furnaces: Viewing ports for monitoring processes up to 1200∘C.

  • High-Power Searchlights: Protective shields for powerful light sources requiring UV stability.

Advantages

  • Superior Optical Performance: High transmission and low distortion across a vast spectrum, ideal for complex optical sensing.

  • Extreme Hardness and Durability: Offers excellent scratch and abrasion resistance, crucial in harsh environments.

  • Thermal Shock Resistance: Withstands rapid changes in temperature, a vital feature for aerospace and industrial use.

  • Precision Polishing: Achieved through advanced CNC machining and fire polishing for a flawless surface finish.

Payment and Shipping

For payment, we accept T/T and L/C. For high-value, sensitive items like quartz domes, we prioritize express air shipping (such as FedEx Priority or dedicated air cargo) to minimize transit time and handling risk. Each dome is individually packaged in anti-static, cleanroom-safe containers within shock-absorbing cases, complete with comprehensive insurance coverage.

  • Q: Can the domes be supplied with an anti-reflective (AR) coating?

  • A: Yes, we offer multi-layer anti-reflective coatings optimized for specific wavelength ranges (e.g., 3−5μm or 8−12μm) to enhance performance and transmission.

  • Q: Are there limitations on the size of the quartz dome you can produce?

  • A: We can manufacture up to 300 mm in diameter for high-precision domes. For larger diameters, please contact our custom fabrication team.
