High-Performance Quartz Windows for Optical, Scientific, and Industrial Applications
Product Overview
Our UV grade fused silica quartz windows are precision-engineered for applications requiring exceptional optical clarity, thermal stability, and chemical resistance. Designed for advanced optical systems, photonics, semiconductor processing, and high-temperature industrial equipment, these windows offer reliable performance across UV, visible, and near-infrared wavelengths (180–2500 nm) with transmittance exceeding 90%.
Standard windows are manufactured in JGS1 type, with custom JGS2 and JGS3 types available upon request. Thicknesses are typically 3–4 mm, but can be customized to meet specific application requirements. Size customization is also available to suit specialized optical, laboratory, or industrial setups.
Featuring a combination of low thermal expansion, high mechanical strength, and excellent chemical resistance, these windows maintain stability under high temperatures, thermal cycling, and harsh operating conditions. They are ideal for applications where precision, durability, and optical performance are critical.
