​​Customized Quartz Optical Windows Fused Silica Plates JGS1 / JGS2 Grade

​​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.

Specification for Quartz Glass Windows

Key Features of Quartz Glass Windows

1. ​​High-Temperature Resistance​​

· Softening point: ~1730°C; long-term operational temperature: up to 1100°C; short-term tolerance: ≤1450°C.

· Withstands rapid thermal cycling (e.g., 1100°C → ambient water) without cracking.

2. Chemical Inertness​​

· Resists most acids (except hydrofluoric acid and phosphoric acid above 300°C).

· Corrosion resistance exceeds ceramics by 30× and stainless steel by 150×.
