Synthetic Sapphire

Synthetic sapphire is a synthetic single‑crystal alumina (Al₂O₃) grown by oriented crystal growth, with a dense, grain‑boundary‑free structure. This single crystal sapphire material offers excellent optical transmission, very high hardness and outstanding chemical and thermal stability. Companion supplies precision sapphire windows, sapphire discs and sapphire rods, and can customize sapphire optical components in various shapes and sizes to meet diverse engineering requirements.
