FUYAO QUARTZ specializes in high-precision quartz glass components. Our custom-shaped quartz through-hole plates are manufactured from high-purity fused silica (SiO₂ ≥ 99.99%) using advanced laser drilling, CNC machining, and optical polishing. These components are designed for demanding applications requiring thermal stability, optical clarity, and chemical inertness.
Features:
-
Custom Through-Hole Designs: Circular, square, spiral, bifurcated, or other complex apertures (0.2–50 mm), with ±0.01 mm positional accuracy.
-
Extreme Thermal Stability: Short-term tolerance up to 1200°C, long-term operational stability 800–1000°C, low thermal expansion coefficient for stress-free performance.
-
High Optical Performance: Transmittance ≥90% in UV (185 nm), ≥95% in visible (400–700 nm), ≥85% in IR (up to 3500 nm). Low scattering and high uniformity ensure precise light path control.
-
Material Purity: SiO₂ ≥99.99%, minimal impurities (<5 ppm), resistant to acids (except HF), alkalis, and organic solvents.
-
Precision Processing: Laser drilling for smooth, stress-free holes; surface roughness Ra ≤0.5 nm (optical grade).
-
Surface Treatment Options: Anti-reflective (AR), high-reflective (HR), and laser damage-resistant coatings. Optional chamfer (<0.2 × 45°) to reduce stress.
