Sodium Chloride – NaCl
lenses, windows, mirrors, filters and prisms
Sodium Chloride is commonly known as rock salt, it is hydroscopic and highly soluble in water. Available in large diameters for use as infrared optical windows, lenses and prisms. To maintain polished surfaces components should be stored and ideally used in a dry atmosphere.
