GENERAL INFORMATION
Magnesium fluoride is by far the most used low index material in the wavelength region UV-NIR. In the IR above 4 µm, Magnesium fluoride is usually not applied since thicker layers show intrinsic stress and thus tend to crack. MgF2 LO (Low Oxygen) has a reduced oxygen contamination level compared to our standard MgF2 products which can be advantageous in highly absorption and defect critical applications.

AREAS OF APPLICATION
- Antireflection (AR) coatings on glass for VIS and NIR
- Multilayer coatings for beam-splitters, filters
- Low index material for UV excimer laser wavelengths, e.g., at 157 nm and 193 nm
- Protective layers, e.g., on aluminium
