Global optical coatings market will reach $ 7.4 billion in 2012

The use of nanotechnology, display technology and the development of biotechnology, optical coatings market will reach $ 7.4 billion in 2012. Requirements for electronic equipment, medical and transportation will drive market growth. Market Report noted that due to the continuous development of technology optical coating ensures that contributions from new markets and business opportunities. magnesia optical films are used in various sectors, including chemical, environmental protection, abrasion resistance, EMI shielding, climate control, Bio-Protection, the temperature, the plurality of optical elements and filters. The demand for various electronic devices such as flat panel displays, laser optics, computers, television screens and cameras will promote market development.A key feature is the coating of optical surface quality. Determine the quality of optical surfaces. A film of high optical quality starts to cool optically smooth surface and its roughness is 0.05 nm. Conventional optical roughness of the coating increases the surface roughness depends on the technology used. For example, evaporation coating technique deposited nm typical surface roughness, typical of ion assisted deposition technique to obtain a surface roughness of 0.4 nm. Ion sputtering of the surface roughness of the thin film of nickel oxide and supports equivalent of 0.05 nm super-polished.As an important branch of modern optics, optical coatings prepared with the wave theory of light and the theoretical basis. Optical coatings are widely used in various optical devices (eg a laser resonator, filter noise and optical lenses, etc.)., Their role in the electrical field is gradually recognized. The United States is the largest market in the world optical layer. The market share in 2008 was approximately $ 2.81 billion. Another is the demand in Asia, after a third of European consumption. Asian markets accounted for 86% of the total world market. The market value of the film transmission and reflection is about $ 3 billion in 2008. The global market for reflection film is expected to reach $ 699 million in 2012.
