Magnesium Fluoride (MgF2) is a proven material for high-energy lasers, especially for lasers operating in the UV range. Typically, the working surface of all optics is perpendicular to the c-axis MgF2 crystal. We provide our customers with excellent quality MgF2 windows.

1. Very hard and strong; 2. Mechanical and thermal shock resistance; 3. The only optical material that combines a broad spectral transmission band with birefringence.
Magnesium fluoride windows are especially useful for lasers operating in the UV range.
