1. High Temperature & High Pressure – First Choice for Extreme Conditions

• Long-term heat resistance up to 1100°C, short-term up to 1450°C
• Excellent pressure resistance — withstands high pressure in autoclaves and pipelines
• Remains structurally stable at high temperatures — no softening or deformation. Ordinary glass softens at 500°C, while quartz windows keep working above 1000°C

2. Thermal Shock Resistant – Safe, No Cracking

• Ultra-low thermal expansion coefficient (only 1/20 of ordinary glass)
• Withstands drastic temperature changes without cracking
• Ideal for batch production equipment with large temperature fluctuations

3. Full-Spectrum High Transmittance – Clear & Accurate Observation

• High transmittance across the full UV-to-IR spectrum
• Visible light transmittance > 90%
• No distortion, no chromatic aberration — true-to-life, clear observation
• Supports UV inspection, infrared temperature measurement and other optical measurements

4. Strong Corrosion Resistance – Superior Chemical Stability

• Resists strong acids (except hydrofluoric acid) and weak alkalis
• No reaction with chemical materials at high temperatures
• No leaching or contamination — suitable for chemical, pharmaceutical and food industries
• Service life far exceeds tempered glass and borosilicate glass

5. Ultra-High Purity – Zero Contamination

• SiO₂ purity ≥ 99.99%
• No impurity release — never contaminates the observed medium
• Standard choice for high-cleanliness sectors such as semiconductor, photovoltaic and pharmaceutical

6. High Strength – Safe & Reliable

• High mechanical strength and good impact resistance
• Thickened versions available for high-pressure applications
• Sealed with metal flanges for safe, stable installation

7. Complete Size Range – Deep Customization

• Shapes: round, square, custom-shaped
• Sizes: diameter φ10mm – φ300mm (larger available on request)
• Thickness: 1mm – 30mm
• Processing: double-side polishing, chamfering, drilling, coating (AR / reflective)
• Accessories: stainless steel flanges and sealing rings available
