MgF2 Optical Window
Magnesium fluoride (MgF2) is a white crystalline salt composed of one magnesium ion and two fluoride ions, and is used in the electrolysis of aluminium ore and anti-reflective coatings. It is a tetragonal, birefringent crystal. MgF2 material is resistant to mechanical and thermal shock, it transmits well into the ultraviolet region. It transmits well into the VUV region to the hydrogen Lyman-alpha line(121nm) and beyond.
MgF2 windows are well suited for deep-UV applications, even extending into the vacuum-UV region. They offer >50% transmission at 120 nm, making them suitable for use with excimer laser systems, as well as applications involving the Hydrogen Lyman-α line at 121 nm. Thorlabs’ MgF2 windows are also usable in the UVA, UVB, visible and IR ranges, with approximately 94% transmission from 200 – 1000 nm, and approximately 95% transmission from 1 – 6 µm.
