Quartz Glass Disc

Quartz glass discs are produced from high-purity fused silica, featuring excellent UV transmission, low thermal expansion, high thermal resistance, and superior chemical stability. With precise surface finishes and customizable dimensions, these discs are widely used in optical components, laboratory instruments, semiconductor processing, and high-temperature settings.
We offer full customization of diameter, thickness, surface finish, flatness, drilling, edge polishing, and CNC machining to meet diverse application requirements.


we can customized all kinds of quartz glass product service
