Infrared Optical Materials
Sapphire is a kind of optical material with excellent performance, high hardness, stable chemical properties, and mature marketization. It is mainly used for semiconductor substrates, optical windows, etc.
Main growth mode
Kyro Poulos method: mainstream, 70% of semiconductor substrates are grown by Kyro Poulos method, maximum weight: 700KG.
Pulling method: can prepare different crystal orientations, with the best optical performance.
Heat exchange method: high preparation cost and low internal thermal stress of the finished product
Guide mold method: low cost, capable of preparing large sizes, commonly used for transparent armor applications.
Anticipation Photonics ’strategy partner can provide large-sized sapphire flat plates with a maximum size of 1500mm * 400mm * 15mm, which can be used for transparent armor, aircraft windows, etc.
Another senior partner is one of the few in the world who can provide ultra large ultra hemispherical sapphire optical products and metal substrates that correspond to usage scenarios.
