Synthetic single-crystal sapphire (Al2O3) is the leading material for highly advanced optical applications due to a unique combination of excellent optical, physical and chemical properties. It is transparent over a wide range of wavelengths from vacuum ultraviolet to infrared regions (from 0.18 µm to 6 µm). Due to its hexagonal crystalline structure, sapphire shows anisotropic behaviour in its optical and physical properties. Therefore the exact characteristics of optical components made from sapphire depend on the crystallographic direction relative to the optical axis (C-axis, 0001). Sapphire possesses birefringence on all directions except for the c-axis. Sapphire is the hardest among all oxide crystals. Due to its extreme surface hardness, sapphire can be scratched by only a few substances (for example, diamond and boron nitride). It's great strength allows for the production of much thinner optical windows compared to other materials. Yet another reason to employ sapphire at wavelengths close to the transmission limit.
