Corrosion-resistant quartz windows are precision optical components made from high-purity fused silica (SiO₂ ≥ 99.99%). These windows combine excellent chemical stability, high optical clarity, and superior thermal resistance, making them suitable for harsh industrial environments and high-precision optical systems.
Our JGS1 and JGS2 quartz glass grades are manufactured using electric fusion and can be provided in standard or custom shapes. These high-transmittance quartz windows are ideal for applications that demand both durability and exceptional optical performance, including planar substrates, sight glasses, lenses, tubes, domes, and other custom components.

Câu hỏi thường gặp
Q1: What makes this quartz glass corrosion-resistant?
Its high chemical purity and network structure make fused quartz highly inert to most acids and bases, excluding hydrofluoric acid. It outperforms borosilicate and soda-lime glass in chemical resistance.
Q2: Can I request custom shapes or dimensions?
Yes. We provide CNC shaping, waterjet cutting, ultrasonic drilling, and thermal forming. Submit your drawing or CAD model for a quotation.
Q3: Is this quartz glass suitable for high-temperature applications?
Yes. Continuous operation up to 1,100°C and short-term exposure up to 1,250°C, with excellent thermal shock resistance.
Q4: Does this quartz glass support UV transmission?
Yes. The high-purity fused quartz transmits UV down to 200 nm, suitable for UV curing systems, monitoring windows, and spectroscopy.
Q5: What are the lead times?
Standard in-stock shapes can be delivered within 3–7 working days. Custom parts typically require 2–4 weeks depending on complexity and volume.
