magnesium fluoride optical coating material is the essential material used for the production of optical lenses and other optica

in order to solve the sputter problems of collapse point of magnesium fluoride optical coating materials, our technicians use techniques like advanced high-temperature air drying, vacuum furnace fluoride, melting, mineralization, crystallization process, precision grinding, screening and so on.

technology

magnesium fluoride optical coating material is the essential material used for the production of optical lenses and other optical components. optical manufacturers have been using it to increase the transmission rate of optical lens, and to improve performance and qualities of camera and optical instrument, because among all the inorganic materials, it has the lowest refractive index and the most stable properties.

the process is simple. just heat and evaporate magnesium fluoride in a vacuum coating machine using tungsten, molybdenum boat or electron gun, and then apply the coating to optical lens. however, the biggest problem in this simple process is the collapse point. high quality lens will become waste products because of collapse point. for the time being, that is one of the main reasons resulting in the cost increase of optical productions.

the collapse point of magnesium fluoride optical coating materials can be caused by many reasons. there are many reasons can cause produced, point of collapse for many reasons. in terms of material itself, it is related to a series of factors, such as the material’s particle size, purity, impurity varieties, crystalline state and etc.

application:

used as fluxing agent for smelting metal magnesium, the additive for eletrolysizing aluminum, also applied to enamels and glass industry, reagent for optical spectrum, and electronic industry.
