NaCl
Crystals such as sodium chloride, potassium bromide and potassium chloride are uniform, bright and high transmittance within 0.250-20 μm when thickness less than 10mm, and no impurity absorption. These single crystals are idea materials for making optical elements for prisms, lenses, filters, and various pool and laser windows in infrared devices and optical instruments.
