High-purity magnesium fluoride optical coating material

The latest research results fill the gaps in the industry of china, its performance indicators have reached to international advanced level.High-purity magnesium fluoride coating materials is the optical lens, laser devices, integrated optics and optical communications major areas of optical coating materials. In recent years, with the development and use of optical coating materials, the further deepening of magnesium fluoride coating materials have been used as important raw material anti-counterfeiting technology notes, Magnesia which more and more widespread attention. China's low-purity magnesium fluoride materials, coating, when collapse points, optical coating industry and has long been almost two years to release a new version of the RMB using the light color ink required for security of high-purity magnesium fluoride optical coating materials have to rely on imports.In order to deal with the technical problems of quality of the magnesium fluoride optical coatings, China in 1994 began to organize some of the optical coating material fluoride experts and experts to carry out a special research workinhigh quality optical crystal magnesium fluoride coating.In1999, relevant units and organizations funded under the project for further research and development work. Through the tireless efforts of researchers, by vacuum melting process refining method to solve the raw materials of different purity of the problem developed special optical coating materials of high purity magnesium fluoride. Double-crucible zone melting method for continuous drain injection material preparation, Titanium dioxide single-furnace production has reached 80kg / furnace. Making use of the method of production of high purity magnesium fluoride optical coating materials in the elimination of the collapse of the critical point to obtain a major breakthrough in technology, product purity up to 99%. And its production process maturity, meet or exceed the world's leading Japanese companies such as Canon technology.The coating material has the characteristics of high output, low power, low cost and stable performance. Currently, the optical anti-counterfeiting materials have been sold to dozens of manufacturers of Guangzhou, Shenyang, Xuzhou, Henan and other places with favorable results. Development and production of the products not only meet the needs of China's defense industry, optoelectronics optical coating industry and civil industry, but also makes the security technology improved greatly. At the same time, it will improve the competitiveness of China’s related products in international markets and earn foreign exchange through export. Source:http://www.mhcocm.com
