Structure: It has a tetragonal crystal structure, which contributes to its unique optical properties, including a wide transparency range.
Optics and Coatings: Due to its wide transparency range, MgF2 is frequently used for lenses, windows, and prisms in optical devices, including cameras, telescopes, and laser systems. It is often applied as a thin coating to reduce reflections on lenses and screens.
UV Optics: Magnesium fluoride’s UV transparency makes it ideal for UV optics and instruments, such as spectrometers, where accurate UV light transmission is critical.
High-Temperature Applications: MgF2 can withstand high temperatures and is used in some specialized applications in aerospace and high-temperature electronics.
MgF2 can be manufactured into lenses, prisms, or coatings through processes like vacuum deposition or sintering. Its high melting point (1,261°C) allows it to withstand the demands of high-temperature environments, but its brittleness requires careful handling during shaping and polishing.
