Sapphire is a single crystal form of Al2O3, with a favorable combination of chemical, mechanical and optical properties. Sapphire is resistant to attack by strong acids, enabling use in a corrosive atmosphere. It is resistant to scratch and abrasion with very high Knoop hardness of 1800 parallel to the optic axis (C-axis), 2200 perpendicular to the optic axis. Sapphire's hardness allows it to be made into much thinner optics than other substrates. Sapphire is chemically inert and insoluble to water, common acids, and alkalis for temperatures up to 1,000 °C. Zoolied Sapphire Rod lenses are transparent in the UV to the IR (150?nm - 4.5μm). It is commonly used in IR laser systems and has an ordinary refractive index of 1.754 and an extraordinary refractive index of 1.747 at 1.064 μm.
