Magnesium Fluoride (MgF2) is commonly used for optical components in wide spectrum band from the vacuum ultraviolet to the infrared, since it is transparent over the entire range of wavelengths (from 0.11-0.12 µm to 7.5-8.0 µm).
Magnesium Fluoride combines wide spectral transmittance band with birefringence phenomenon. Its birefringence makes polarizing optics for the ultraviolet region possible. With Lithium Fluoride it is one of the two materials that will transmit in the vacuum ultraviolet range at the hydrogen Lyman-alpha line (121nm).
Magnesium Fluoride is tough, it is used if extreme ruggedness and durability is required. It is resistant to thermal and mechanical shock. Irradiation doesn't lead to color centers.
Magnesium Fluoride is used for the production of windows, prisms, lenses and other optical items in the range from the vacuum ultraviolet to the infrared.
We use for our optics high quality crystals growth on the Czochralsky and Bridgman Methods and supply high transparency and low loss optical windows, prisms, lenses, achromatic lenses and other optical components. Magnesium Fluoride is sold in two qualities (monodomain and polydomain) and in three grades - IR, UV and VUV-grade.
