LiF Windows

LiF Windows

Lithium fluoride is a tetragonal crystal system, the crystal growth can be single polycrystalline blocks or directional growth of single crystals. Therefore, there is a difference between monocrystalline and polycrystalline lithium fluoride. Polycrystalline lithium fluoride is mostly used as protective windows; monocrystalline lithium fluoride is suitable for lenses, prisms and observation windows.
