Fused Quartz Windows Key Characteristics
1. Intrinsic Properties of the Quartz Wafer
- Piezoelectric Effect: Mechanical stress applied along the X/Y-axis generates charge (reverse piezoelectric effect), while an external electric field induces deformation. This principle underpins the fabrication of resonators and filters.
- High Transmittance: Fused quartz windows visible light transmittance >85%, with excellent transmission in the ultraviolet range (185–250 nm), ideal for optical detection and laser systems.
- High-Temperature Resistance: Fused quartz windows long-term operational temperature up to 1,100°C; short-term tolerance up to 1,450°C. Low thermal expansion coefficient (~5.5×10⁻⁷/°C) ensures stability in high-temperature environments.
- Chemical Stability: Fused quartz windows resistant to strong acids (except hydrofluoric acid), outperforming ceramics and metals in corrosion resistance.
2. Dimensional Design Advantages
- Thickness of 2.95mm: Fused quartz windows optimized ratio of thickness to diameter balances mechanical rigidity and frequency stability, suitable for precision oscillators (e.g., TCXO, VCXO).
- Diameter of 35.04mm: Fused quartz windows large size minimizes edge effects and enhances optical uniformity, ideal for large-area optical windows or wafer-level processing.
Fused Quartz Windows Key Applications
1. Communications & Electronics
- High-Frequency Resonators/Oscillators: Generate stable frequency signals via piezoelectric effects, fused quartz windows used in 5G base stations, satellite communications, and radar systems.
