Customized Quartz Optical Windows Fused Silica Plates JGS1/JGS2
Grade
Quartz glass window plates are precision-engineered optical
components manufactured from high-purity silicon dioxide (SiO₂). Renowned for their exceptional optical transparency, thermal
stability, and chemical inertness, these plates exhibit
broad-spectrum transmission (185 nm to 3500 nm) and ultra-low
thermal expansion coefficients (5.5×10⁻⁷/°C), making them ideal for
extreme environments. As an integrated manufacturing and trading enterprise, ZMSH
specializes in R&D, production, and customization of quartz
glass window plates, offering tailored solutions (e.g., dimensional
specifications, surface coatings, and geometries). Products serve diverse sectors, including semiconductors, laser
systems, aerospace, medical devices, and renewable energy, with a
global distribution network spanning domestic and international
markets.
