High-purity quartz glass plates for semiconductor and optical applications.

High-Purity Quartz Glass Plates

We engineer our High-Purity Quartz Glass Plates for superior performance in mission-critical systems. Specifically, these plates deliver a unique combination of exceptional thermal stability and broadband optical transmission. We manufacture them from select-grade Quartz Glass, thus making them a foundational component for demanding semiconductor and optical applications. Whether you require ultra-flat substrates or durable viewports, our plates consequently provide a reliable, custom-fabricated solution.

Our Quartz Glass Plates are distinguished by their exceptional material properties. For example, key advantages include ultra-high purity (≥ 99.99% SiO₂) to prevent process contamination and outstanding resistance to thermal shock. In addition, we offer comprehensive custom fabrication services, including advanced CNC machining, to meet your exact specifications.

Material Science and Manufacturing Excellence

The superior performance of our Quartz Glass Plates begins with the material itself. Indeed, we utilize only the highest-grade Quartz Glass, which features an amorphous, non-crystalline structure. As a result, this structure yields isotropic properties, meaning its physical characteristics are uniform in all directions. Furthermore, our advanced manufacturing processes translate this material advantage into a final product with outstanding dimensional accuracy and minimal stress. From protective windows in plasma environments to ultra-flat substrates for thin-film deposition, we therefore engineer each plate to provide a contamination-free and stable solution for your most critical processes.
