MgF2
MgF2 is positive uni-axial crystal with a very high optical transmittance from the vacuum UV to IR. It also has a large resistance to mechanical and thermal shock, to optical radiation, and is chemically stable, making it a very useful materials for UV and IR optics.
Property:
l >50% Transmission at 120 nm
l Transmission ≥94% for λ = 200 nm - 6 µm
l Suitable for Excimer Lasers and Other Deep UV Applications
Advantages:
l High optical transmittance from the vacuum ultraviolet to the infrared spectrum region(0.12～8.5μm).
l Resistant to mechanical and thermal shock, to radiation
l Chemically stable
l A positive birefringent crystal, used for optical fiber communication
l Used for Optical prisms, lenses, wedges, windows, other optical components and etc
