Sapphire Prism
Sapphire is a single crystal aluminum oxide (Al2O3). It is one of the hardest materials and ranks a 9 on the Mohs scale. Sapphire offers good transmission characteristics over the visible, and near IR spectrum. Due to its high mechanical strength, chemical resistance, thermal conductivity, and thermal stability, Sapphire is ideal material for optical prism used in a specific field such as space technology where the scratch or high-temperature resistance is required. 
UltiTech offers a wide of high quality sapphire prisms, such as right angle prisms, penta prisms, dove prisms, roof prisms, rhomboid prisms or custom shapes.
