Sapphire Windows

Sapphire windows are optical components, made from high-purity single-crystal alumina (Al₂O₃) grown with controlled crystal orientation and finished by ultra-precision optical polishing. These optical-grade sapphire windows combine good transmission, surface hardness and chemical inertness. They withstand high vacuum, high temperature, aggressive chemicals and abrasion, serving as durable viewing ports and optical components for precision equipment, laser systems, analytical instruments and advanced electronic process tools. Sapphire windows help enhance system reliability and process stability in harsh industrial and high-end manufacturing environments.

Size：Customized on demand

Customize：Can be customized and reverse developed according to drawings and samples.
