Alkor Technologies - manufacturer of Magnesium Fluoride windows.

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

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. Often used as UV viewports. Standard orientation of the crystal is c-cut to minimize berefringence.

Custom sizes and specifications of MgF2 window and MgF2 wedge are available. Contact us today and save up to 60% from major optical catalogs price on Magnesium Fluoride windows!
