Birefringent Crystal MgF2

Overview:

Magnesium Fluoride (MgF2) is good birefringent crystal with good transmission over 120-7000nm. It is a hard material which is resistant to thermal and mechanical shock and can be worked according to the highest standards. MgF2 single crystals is a positive birefringent crystal and widely used for Optical prisms, lenses, windows and other optical components.
