Magnesium Fluoride (MgF2)

Magnesium Fluoride (MgF₂) is a highly valued optical material widely used in windows, lenses, and prisms for applications spanning the ultraviolet (UV) to the mid-infrared (IR) spectrum, typically from 120 nm to 7 µm. Known for its excellent UV transmission and low refractive index, MgF₂ minimizes chromatic aberration, making it ideal for UV spectroscopy, excimer laser systems, and high-precision optical instruments. Its outstanding durability, resistance to thermal shock and radiation damage, and mechanical strength make it a preferred choice in aerospace, defense, and scientific research where rugged, high-performance optics are essential
