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.
