Magnesium fluoride is a kind of inorganic compound, chemical formula is MgF2, it is a kind of white crystal, with cubic crystal system structure, lattice constant is 4.64 Å. Magnesium fluoride has good optical properties, its refractive index with the wavelength of the law of change is similar to the change of the air, and in the ultraviolet to the near-infrared range has a high transmittance rate. In addition, magnesium fluoride has a small coefficient of thermal expansion and excellent thermal and chemical stability.
