Magnesium Fluoride – MgF2
lenses, windows, mirrors, filters and prisms
Magnesium Fluoride is a very durable material, resistant to mechanical and thermal shock and used for prisms, windows and lenses from the vacuum ultraviolet to the infrared region of 7.5 microns. MgF² is a birefringent material making it effective as a polarising element in the ultraviolet region.
