Magnesium fluoride (MgF2)

Magnesium fluoride (MgF2) is an important optical crystal. Because of its excellent optical properties and excellent mechanical properties, it has been widely used in the field of optics

The characteristics of Magnesium fluoride crystal are mainly reflected in its excellent transparency and low reflectivity. It ranges from vacuum ultraviolet (110nm) to infrared (8 μ m) It has high transparency over a very wide wavelength range, making it an ideal material for many optical components. In addition, due to its low refractive index (approximately 1.38 in the visible light region), MgF2 can be used as an anti reflective coating in optical components, greatly reducing reflection loss and improving the performance of optical systems< Br/>

Magnesium fluoride is a Orthorhombic crystal system crystal with lattice parameters a=4.64 ∨, b=4.64 ∨, c=3.09 ∨. This crystal structure provides MgF2 with excellent thermal and chemical stability, while also ensuring its stability under certain pressures and being less prone to breakage< </>

Magnesium fluoride crystals are widely used to manufacture high-quality optical components, such as lenses, windows, prisms, and reflectors.

. In addition, it is also used as an optical coating to improve the transmission efficiency and reflection performance of other optical components. Due to its excellent ultraviolet transmission performance, MgF2 crystals are also commonly used in fields such as ultraviolet imaging and spectral analysis The development prospects of MgF2 crystals are very broad. With the development of optoelectronic technology, the requirements for optical components are becoming increasingly high, and magnesium fluoride crystals are expected to play a greater role in such applications due to their excellent performance. Meanwhile, with the progress of production technology, it is expected that the manufacturing cost of MgF2 crystal will be further reduced, allowing it to be applied in a wider range of fields
