Product Family Description

Excellent Transmission from 120nm to 7μm
Rugged and Durable
Resistant to Chemical Etching

TECHSPEC® 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.
