Sapphire is a single crystal aluminum oxide (Al2O3). It is one of the hardest materials. Sapphire has good transmission characteristics over the visible, and near IR spectrum. It exhibits high mechanical strength, chemical resistance, thermal conductivity and thermal stability. It is often used as window materials in specific field such as space technology where scratch or high temperature resistance is required.

Sapphire Window

Sapphire window is made from synthetic sapphire and can be made much thinner than BK7 windows..  It is highly durable with a wide transmission range. Sapphire window is best suited for scratch resistance application that requires better transmission over a wide range spectrum.
