Laser-cut quartz plates are high-precision components crafted from high-purity fused silica (SiO₂ ≥99.99%) using advanced CO₂ or ultrafast laser technology. This non-contact processing method preserves the material’s intrinsic properties while delivering micron-level dimensional accuracy, making it the preferred choice for high-end industrial, optical, and semiconductor applications.
Core Performance
1. Exceptional Dimensional Precision
Cutting tolerance as tight as ±0.01 mm, with kerf width < 0.1 mm and edge chipping ≤ 5 μm. Enables complex shapes (circles, rectangles, irregular contours) that are difficult to achieve with mechanical cutting.
2. Minimal Thermal Impact
Advanced laser processing results in a narrow heat-affected zone (HAZ) and negligible thermal deformation. The non-contact method eliminates mechanical stress, preventing micro-cracks and ensuring structural integrity.
3. Superior Optical Transmittance
Maintains the material’s inherent optical performance: >90% transmittance from UV (190 nm) to near-infrared (2500 nm). Ideal for high-energy laser systems and UV optical applications.
4. Extreme Thermal Shock Resistance
Ultra-low thermal expansion coefficient (5.5×10⁻⁷/°C), allowing it to withstand rapid temperature cycles from -200°C to 1100°C without cracking.
5. Outstanding Chemical Inertness
Resistant to most acids, alkalis, and organic solvents (except hydrofluoric acid). Suitable for corrosive environments in chemical processing and semiconductor manufacturing.
6. High Mechanical Strength
Retains the material’s natural hardness (Mohs 7) and flexural strength, which even increases at high temperatures (30%–60% higher at 1000°C than at room temperature).
Key Applications
1. Semiconductor & Photovoltaic
Precision carriers, wafer inspection windows, and lithography mask substrates. Critical for high-purity processes such as etching, deposition, and wafer dicing.
