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.

SSS
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.
