Description

Fused Quartz Windows Product Introduction

High-Purity Fused Silica Window Quartz Crystal Glass Diameter 35.04mm Thickness 2.95mm

High-Purity Fused Silica Window Quartz Crystal Glass Diameter 35.04mm Thickness 2.95mm

This quartz wafer is manufactured from high-purity silicon dioxide (SiO₂ ≥ 99.99%) and exhibits exceptional physicochemical stability, making it suitable for high-frequency, high-precision electronic devices and optical systems. Its dimensions (35.04mm diameter, 2.95mm thickness) balance mechanical rigidity and frequency stability, meeting the demands of compact, high-performance precision instruments.

ZMSH's Business Expansion:

​​

In addition to custom sapphire products, our company offers comprehensive quartz material processing services, including quartz wafers, quartz boats, quartz tubes/rods, and quartz optical windows. These products serve diverse sectors such as semiconductors, optoelectronics, and medical devices. Examples include:

  • ​Quartz Wafers​​: Used as carriers for semiconductor wafers and photolithography mask substrates.
  • ​​Quartz Optical Windows​​: Applied in lasers and fiber-optic communication systems as infrared/ultraviolet-transmitting components.
  • ​​Quartz Tubes/Rods​​: Utilized in high-temperature reaction vessels and optical instrument light-guiding components.

Fused Quartz Windows Key Characteristics

1. ​​Intrinsic Properties of the Quartz Wafer​​

High-Purity Fused Silica Window Quartz Crystal Glass Diameter 35.04mm Thickness 2.95mm

  • ​​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.
  • ​​Filters​​: Selective signal filtering through precise cutting (e.g., AT-cut, SC-cut) improves anti-interference capabilities in communication devices.

2. ​​Optics & Laser Technology​​

  • ​​Laser Cavity Mirrors​​: Fused quartz windows serve as reflective mirrors in laser resonators to stabilize beam modes.
  • ​​Fiber-Optic Connectors​​: Enable low-insertion-loss coupling at fiber ends (e.g., SC/APC interfaces).

3. ​​Industrial & Scientific Instruments​​

  • ​​Spectrometers​​: Fused quartz windows act as dispersive elements to isolate specific wavelengths (e.g., UV-vis spectrophotometers).
  • ​​High-Temperature Sensors​​: Monitor temperatures in molten metals or chemical reactions leveraging thermal resilience.

4. ​​Medical Devices​​

  • ​​Medical Imaging Systems​​: Optical components in MRI and CT scanners for high-resolution imaging.
  • ​​Biological Assay Instruments​​: Fused quartz windows as transparent substrates for optical detection modules to enhance sensitivity.
