MgF2 crystals is positive uni-axial crystal with a very high optical transmittance from the vacuum UV to IR, its useful transmission range is 0.12 m - 8.5μm, irradiation does not lead to color centers. MgF2 is a chemically stable, hard material which is resistant to thermal and mechanical shock, it is a positive birefringent crystal grown normally to big diameter by vacuum Stockbroker technique, seeding along the C-axis.


MgF2 is a popular choosed material for UV and excimer laser windows, polarizers, prisms, lenses, wedges, windows, and other optical components。
