Magnesium Fluoride Crystal

Magnesium Fluoride Crystal (MgF₂) belongs to tetragonal crystal system, with melting point of 1255 °C, high hardness, good mechanical properties, stable chemical properties and not easy to deliquescence and corrosion. In terms of optical properties, it is mainly characterized by high transmittance in vacuum ultraviolet band (the transmittance of 170 nm is still more than 70%), which is widely used in optical fiber communication, military industry and various optical components.

Advantages of MgF₂:

1. High optical transmittance from the vacuum ultraviolet to the infrared spectrum region (0.12-8.5 μm).
2. Resistance to mechanical, thermal shock and radiation
3. Chemically stable
4. A positive birefringent crystal
5. Used for Optical prisms, lenses, wedges, windows, other optical components etc.

NCE supplies high quality MgF₂ Magnesium Fluoride Crystal in mass production quantity. Material from NCE features with high transmittance in VUV (>70%) and UV wavelength ranges. Standard size for VUV windows are Dia.8 and Dia.6 with 1 mm thickness.

NCE offer both a-cut (or [100] cut) MgF₂ windows for the maximum birefringence and c-cut (or cut along the optical axis) with the minimum birefringence. Random-cut (cut along a random axis) MgF₂ windows are also available. The thickness can be made as thin as 0.1 mm. In addition, we can also provide other types of window crystals like YAG crystals, BaF₂, LiF crystals, etc.

NCE has a mass-production line for MgF₂ crystals and have wide experiences and strong ability to supply such crystals with large quantity and in short delivery time. Please contact us for more details. Get a Quote Now! For other optical materials, please check our Optical Materials category page.

Other Trade Name: Single Crystal MgF₂

Typical Applications of MgF₂:

MgF₂ or Magnesium Fluoride is positive uni-axial crystal with a very high optical transmittance from the vacuum UV to IR. It is regularly used for optical elements where extreme ruggedness and durability is required. 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.
