Magnesium Fluoride (MgF2) is a colourless, hard and durable material and is birefringent. The material's durability and resistance to mechanical and thermal shock enable it to be used in harsh conditions, in the form of windows, while its birefringence makes it useful for polarizers in the UV waveband. It transmits between 0.1µm and 7µm and at over 90% between 0.4-5.0µm. Magnesium Fluoride has a hardness of about HK576, making it the hardest of the optical fluorides. It is stable in water, which means that it can be used for outer surfaces, such as windows.
Knight Optical supply a range of quality Magnesium Fluoride windows either from stock or custom made to your specification for a range of applications. Every component is individually tested by our highly skilled technicians in our state of the art metrology lab to ensure all components meet our high quality standards.
