Knight Optical Magnesium Fluoride (MgF2) Windows

27 Nov 2019

Known for their resistance to mechanical and thermal shock, our Magnesium Fluoride (MgF2) Windows are specified for a variety of applications operating in a range of harsh environments. Commonly employed for high-tech applications include excimer lasers, Fourier-transform infrared spectroscopy (FTIR), thermography and other infrared (IR) systems, MgF2’s durability and birefringent properties make for a sought-after optical window across a spectrum of industries. What’s more, its stability in water means it’s ideally suited for outer surfaces, such as windows.

 With its birefringence (beneficial for polarisers in the UV waveband), transmittance between 0.1µm and 7µm and at over 90% between 0.4-5.0µm and hardness of circa HK576, MgF2 is one of the hardest optical fluorides. 

 Here at Knight Optical, we stock a wide range of MgF2 Windows suitable for a variety of diverse applications. Furthermore, for applications requiring tailored solutions, we also supply custom-made MgF2 Windows in a range of sizes, shapes, substrates (including infrared [IR] MgF2 materials) and tolerances for seamless integration with any device. Alongside our customised offering, we also supply MgF2 Windows mounted into cells and can edge down stock in-house for quick lead times.
