Magnesium fluoride, MgF2 is a white crystalline salt and is transparent over a wide range of wavelengths, 

with commercial uses in optics that are also used in space telescopes,  

Molar mass 62.3018 g/mol , Appearance white tetragonal crystals , 

Density 3.148 g/cm3 , Melting point 1263 °C , Boiling point 2260 °C 

Uses:

Optics: Magnesium fluoride is transparent over an extremely wide range of wavelengths. 

Windows, lenses, and prisms made of this material can be used over the entire range of wavelengths 

from 0.120 μm (vacuum ultraviolet) to 8.0 μm (infrared). However, with lithium fluoride it is one of 

the two materials that will transmit in the vacuum ultraviolet range at 121 nm (Lyman alpha) 

and this is where it finds its application. 

Lower grade MgF2 is sometimes used in the infrared but here it is inferior to calcium fluoride. MgF2 is 

tough and works and polishes well, but it is slightly birefringent and should be cut with the optic 

axis perpendicular to the plane of the window or lens.

Due to its having a suitable refractive index of 1.37, thin layers of MgF2 are very commonly used on the 

surfaces of optical elements as inexpensive anti-reflective coatings.

The Verdet constant of (MgF2) at 632.8 nm is 0.00810 arcmin G−1 cm−1.
