Information

OFweek optical network news: with the continuous promotion of coating technology, the application field of optical coating technology is also constantly widening. Most of the optical coating materials used in different fields belong to rare metals with very small reserves. These rare metals and rare earths are rarely used in industry, but they are indispensable. They are called industrial vitamins".
In the application of optical coating materials, coating target is the core technology, and the formation of optical coating of different materials by different rare metals with different targets, rare metals commonly used with yttrium fluoride, praseodymium fluoride, magnesium fluoride, germanium, zinc sulfide, titanium dioxide, zirconium oxide, cobalt, gallium and selenium and other metal. The mirror in the optical material widely used in copper, molybdenum, silicon, germanium and other metals in the output and transmission of optical elements in Ge, GaAs and ZnSe widely used etc..
Coating is a physical or chemical method on the surface of the material coated with a transparent electrolyte membrane, or coated with a metal film, the purpose is to change the reflection and transmission characteristics of the surface of the material. Optical coating is in the optical interference principle in the visible and infrared range, the reflectivity between 78-98%, to reach the light transmittance, optical coating technology is an important basic technology can not be ignored in the optical field.
In our daily life, such as optical coating everywhere, usually wearing glasses, digital cameras, all kinds of household appliances, or bill anti-counterfeiting technology, in the field of medical equipment, all kinds of weapons and military fields. The most common thing is to look at the phone screen in the sun, because the reflection light is not strong, the screen is fuzzy, which requires the screen of optical coating to achieve the transmission clear effect.
As an important rare metal materials for optical coating applications, it has penetrated into the high-end technology field, especially play an important and irreplaceable role in national defense, aerospace, precision instrument manufacturing and electronics industry. At present, gallium, germanium, selenium, cobalt and other 14 kinds of rare metals and rare earth has been listed on the Pan Asian non-ferrous metals exchange and Xiashang, and through the pan financial network unique warehouse financing business to ordinary investors directly involved in the rare investment, the combination of industrial capital and financial capital, industrial enterprises and individual investors share resources value-added income from.
