The oldest and simplest optical coating is magnesium fluoride
A deuterium lamp provides the electromagnetic radiation to the flow cell, which is isolated from the source and detector modules by two VUV transparent magnesium fluoride
Superabrasives specialist Engis, has developed a new process for polishing Laser grade-quality optical surfaces, which enables materials including: Zinc Selenide, Zinc Sulfide, Germanium, Silicon, Calcium Fluoride and Magnesium Fluoride
, to be polished using exactly the same diamond slurry and composite plate combination.
The fishnet consists of 20 alternating layers of gold films 30 nanometers thick and magnesium fluoride
films 50 nanometers thick on a 50-nanometer thick silicon nitride membrane.

The family of larger aperture optics consists of two different birefringent crystals - crystalline quartz and magnesium fluoride
(MgF2) - each with a highly efficient broadband antireflection coating, in an air-spaced design.
Metier IR and Broadband Optics are fabricated to specification from calcium fluoride, magnesium fluoride
, germanium, silicon, zinc selenide and zinc sulfide.
Fluoride ions precipitate as insoluble magnesium fluoride
In the ensuing decades, magnesium fluoride
has been joined by many other "rare earths" in very thin layers.
The researches tested this process using different materials such as, magnesium fluoride
, chalcogenide glass and even tape.
The compound induces the production of magnesium fluoride
, which mixes with magnesium oxide to produce a solid solution that takes the form of a thin, flexible layer on the magnesium metal, preventing further reaction between the magnesium and the coating.
SpectraFlair, introduced in 2002, is a three-layer thin-film flake comprised of magnesium fluoride
