Product Description

D60*5mm Polished Magnesium Fluoride (MgF2) Optical Window

MgF2 Window(Magesium Flouride is transparent over a extremely wide range of wavelengths. Mgf2 opticl window, single Crystal Mgf2 Lens and prisms made of this materials can be used over the entire range of wavelengths from 0.12μm(vacuum ultraviolet) to 8.0μm (infrared). High quality synthetic VUV grade MgF2 is quite expensive. Low grade MgF2 is sometimes used in the infrared but it is inferior to CaF2. MgF2 is tough and works and polishes well, but magnesium fluoride windows is slightly birefringent and should be cut with the optic axis perpendicular to the plane of the window or lens.
