Quartz Glass Optical Windows JGS1/JGS2 Grade Coating Optional 8.2mm Thickness
Quartz windows are optical components made from high-purity silicon dioxide (SiO₂), featuring broad-spectrum transmission from UV to IR, high-temperature resistance, and low thermal expansion. These properties make them ideal for scientific research, industrial inspection, laser systems, and medical equipment. The quartz optical window (8.2mm thickness) is a high-purity fused silica (SiO₂) optical element with excellent light transmittance, thermal stability, and chemical inertness, suitable for UV, visible, and IR optical systems. ZMSH offers a full range of quartz windows, including standard sizes (round, square) and customized products (special-shaped, drilled, or irregularly shaped windows), supporting OEM machining to meet stringent optical and mechanical requirements.
