Key Features of Fused Silica Windows (8.2mm & 8.3mm)

​

1. High Transmittance

· Broadband transmission from UV to NIR (190nm–2500nm), particularly optimized for deep ultraviolet (DUV) and infrared optical systems.

· Low absorption rate minimizes energy loss, enhancing system efficiency.

2. Exceptional Thermal Stability

· Ultra-low thermal expansion coefficient (5.5×10⁻⁷/°C) and high-temperature resistance (~1200°C), suitable for high-power lasers and extreme thermal conditions.

· Excellent thermal shock resistance withstands rapid temperature fluctuations without cracking.

3. Superior Chemical Inertness

· Resistant to strong acids, alkalis, and organic solvents, ideal for corrosive environments.

· Optional surface treatments (e.g., AR coatings, hydrophobic layers) for specialized applications.

4. High Laser Damage Threshold

· Compatible with high-energy laser systems (e.g., CO₂ lasers, UV lasers) due to exceptional laser-induced damage resistance.

· Custom optical coatings (e.g., AR, HR) available to optimize transmission/reflection at specific wavelengths.

5. Precision Optical Performance

· Surface flatness up to λ/4 (@632.8nm) and parallelism <3 arcmin, meeting stringent optical alignment requirements.

· Low bubble/impurity content ensures optical uniformity, minimizing scattering and wavefront distortion.

Primary Applications of quartz optical window

1. Laser Optical Systems

· Laser cavity windows, protective optics for high-power laser cutting/welding, and medical laser devices.

· Preferred for UV lasers (e.g., excimer lasers) due to excellent UV durability.

2. Spectroscopic Instrumentation

· Transmission windows for UV-Vis spectrophotometers and FTIR spectrometers, ensuring high signal-to-noise ratios.

· Vacuum ultraviolet (VUV) applications, including synchrotron radiation detection.

3. Semiconductor & Lithography

· Optical components for lithography machines and wafer inspection systems, resistant to DUV radiation and thermal deformation.

· Critical for mask protection and projection optics in advanced nodes.

4. Scientific Research & High-Energy Physics

· Observation windows for particle detectors and synchrotron facilities, combining radiation resistance with high transparency.

· Sealed viewports for vacuum/high-pressure environments (e.g., electron microscopes, plasma experiments).

5. Aerospace & Medical Devices

· Protective windows for aerospace optical sensors, enduring extreme temperatures and cosmic radiation.

· Biocompatible components for endoscopes and medical laser therapy systems.
