Sodium Chloride (NaCl), commonly known as rock salt, is a soft, highly soluble and hydroscopic material. It transmits over a broad wavelength range of about 0.25 to 16μm and is ideal for lenses and other optical components for use the UV and IR range. Sodium Chloride has a maximum operating temperature of 400°C and requires protection from atmospheric conditions due to moisture degradation. Coating is recommended where the material is exposed and a high standard of polish can be achieved under humidity controlled conditions. It has a hardness of HK18.2, which is soft, and therefore requires careful handling.
