​​High Purity Quartz Glass Plate With Laser-Drilled Custom-Shaped Through-Holes​

​​High-Purity Quartz Glass Plate with Laser-Drilled Custom-Shaped Through-Holes​​

Quartz custom-shaped through-hole plates are precision-engineered optical components manufactured from high-purity fused silica (SiO₂ ≥99.999%) using advanced laser drilling, grinding, and polishing techniques. Their core features include:

· ​​Customized through-hole designs​​: Circular, square, spiral, bifurcated, and other non-standard apertures (0.2–100 mm) with ±0.01 mm precision, enabling complex light path control.

​​· Extreme thermal stability​​: Short-term resistance up to 1200°C, long-term operational stability at 800–1000°C, and a thermal expansion coefficient 1/10th of standard glass.

​​· Broad-spectrum transmittance​​: ≥90% (UV: 185 nm), ≥95% (visible), and ≥85% (IR: 3500 nm), ensuring optical purity without bubbles or striations.

​​· Tailored services​​: Support for customer-provided designs (2D/3D drawings), laser drilling customization (e.g., through-holes, countersinks, stepped holes), rapid small-batch delivery (3–5 days), and rigorous quality control (SGS-certified).

​​ZMSH​​ specializes in manufacturing quartz custom-shaped through-hole plates for semiconductor equipment, photonics, and medical instrumentation, integrating design, processing, and testing to meet stringent requirements for precision, high-temperature resistance, and low scattering.
