Infrared optical window

magnesium fluoride (MgF2)

Magnesium Fluoride (MgF2) Windows Magnesium Fluoride Windows applicable for wide range spectrum, transmits well into the VUV region at the hydrogen Lyman-alpha line and beyond and it is particularly useful for Excimer laser application.It is resistant to mechanical and thermal shock, to radiation, and is chemically stable. Product Origin:China Shipping Port:Fuzhou China Lead Time:4 working weeks Payment:T/T Payment, Western Union Magnesium Fluoride (MgF2) Windows offer excellent broadband transmission from the deep-UV to the mid-infrared. DUV transmission makes them ideal for use at the Hydrogen Lyman-alpha line and for UV radiation sources and receivers, as well as excimer laser applications. MgF2 is a rugged material resistant to chemical etching, laser damage, and mechanical and thermal shock. It has a Knoop Hardness of 415 and index of refraction of 1.38.
