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 a specific field such as space technology where the scratch or high-temperature resistance is required.
There are some kinds of high precision prisms, such as right angle prisms, corner cubes, pentaprism, dove prisms, roof prisms, rhomboid prisms or other irregular shapes.
