Magnesium Fluoride Evaporation Materials (MgF₂) are high-purity optical coating materials used for vacuum evaporation, physical vapor deposition (PVD), thin-film optical coatings, anti-reflective coatings, laser optics, lenses, displays, and photonics applications.
MgF₂ is particularly valuable for optical coatings because of its low refractive index, high optical transparency, good transmission in the UV-to-infrared range, and resistance to environmental degradation. It is one of the most widely used materials for anti-reflective optical coatings.
REG Metals supplies high-purity magnesium fluoride evaporation materials for thermal evaporation, electron-beam evaporation, and other vacuum deposition processes. Purity, particle size, geometry, and packaging can be specified according to the deposition system and coating requirements.
