Optical crystals, such as CaF2, BaF2, MgF2, LiF, NaCl, KCl, KBr are widely used in IR optics and UV optics. High transparency and low loss optical windows, prisms, lenses, achromatic lenses and parallel planes have been fabricated in these optical materials. These crystals are widely applied to the entire optical wavelength range, from vacuum ultraviolet (0.11 µm) to far infrared (40 µm). MolTech is ready to meet customers' various requirements for dimensions and other specifications.
Optical quality Sodium Chloride (NaCl) is used for windows, lenses and prisms where transmission in the 0.25 - 16 µm range is desired. Because of its low absorption, Sodium Chloride is being used in high power laser systems. Polished surfaces must be protected from moisture by exposing to only dry atmosphere or by using a heating element to maintain the Sodium Chloride above the ambient temperature. Optical quality Sodium Chloride (NaCl) can be used up to 400°C. Optical quality Sodium Chloride (NaCl) is sensitive to thermal shock. Irradiation of Sodium Chloride (NaCl) generates color centers.
