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.
Key features:
· Excellent Transmission from 120nm to 7μm
· Rugged and Durable
· Resistant to Chemical Etching
