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

Premium Quality quartz glass plates

Engineered for superior performance in demanding environments, our quartz glass plates offer exceptional thermal stability, high purity, and excellent optical transmission. They are ideal for use as viewports, substrates, and windows in semiconductor, optical, and high-temperature furnace applications.

  • Ultra-high purity quartz for minimal contamination.
  • Excellent resistance to thermal shock and chemical corrosion.
  • Superior flatness and surface finish for demanding applications.
  • Custom shapes, sizes, and thicknesses available.

Detailed Description

Our quartz glass plates are manufactured from the highest-grade fused quartz using advanced fabrication techniques. This ensures outstanding dimensional accuracy, chemical inertness, and resistance to high temperatures. Ideal for protective windows, substrates for thin-film deposition, or sight glasses, our plates provide a contamination-free and stable solution for the most critical processes. Each plate is rigorously inspected to meet strict industry standards.
