Sodium Chloride is used for windows, lenses and prisms where transmission in the 0.25 µm - 16 µm range is desired. Because of its low absorption, Sodium Chloride is being used in high power laser systems. Sodium Chloride is produced in large ingots by the Kyropoulos growth method. It cleaves easily. With care it can be polished to a high standard under humidity controlled conditions. Polished surfaces must be protected from moisture by exposing them to only dry atmosphere or by using a heating element to keep the surfaces above ambient temperature. Sodium Chloride can be used at temperatures up to 400 °C. The material is sensitive to thermal shock. Irradiation generates color centers.
