In the optical coating, it is often nothing more than a contact glass, optical aerospace industry for relatively scarce material through the optical film coating system to achieve the effect of a specific function which is the value of the film exists.
The film refractive index mainly to reduce or eliminate reflected light lenses, prisms and other optical surface, the optical element, in order toreduce light reflection loss element, in which a transparent dielectric film surface coating system, known as an anti-reflection or antireflection film, antireflection coating effect is closely related to the refractive index of the film thickness.
Transmittance and optical coating film refractive index-related, then the thickness of the film there is no relationship? In many complex optical systems, inhibition of the emitted light is very important, relatively speaking, the color of the emitted light more advanced optical system will be more and more, after the experiment, the film thickness to substantially affect light transmission is relatively small, if the thickness of the film something down, you will find the emitted light and reflected light a B exist nc * 2D optical path difference.

Analysis Principle vacuum coating equipment

                             Analysis Principle vacuum coating equipment

Principle is the principle of magnetron sputtering vacuum coating equipment , as follows:
Colliding electrons accelerated in the electric field toward the substrate during in and argon atoms, a large number of ionized argon ions and electrons, the electrons onto the substrate. Argon ions accelerated in the electric field bombardment target, a large number of target atoms sputtered, neutral target atoms deposited in a film on the substrate.
Secondary electrons accelerated toward the substrate in the process influenced by the magnetic force of the magnetic field Lorenzi, bound within plasma region near the target surface, a high plasma density region, under the effect of the secondary electrons around the magnetic field the target surface in a circular motion, the motion path of the electrons is very long, constantly in motion the process of collision ionization of argon atoms with a large amount of argon ion bombardment target, after several collisions electron energy decreases, get rid of the shackles of the magnetic field lines , away from the target, eventually deposited on the substrate.
Magnetron sputtering is bound to a magnetic field and to extend the path of movement of electrons, the electrons change the direction of motion, increase the ionization rate of the working gas and the efficient use of energy of the electron vacuum coating apparatus.
Electronic destination just substrates, the vacuum chamber wall and the target source anode is electronic home. But generally the vacuum chamber and the substrate and the anode potential in the same. Interaction between magnetic field and electric field so that a single spiral electron trajectory in three dimensions, and not only in a circular motion in the target surface. As for the type of the target surface sputtering the circumferential contour, and that the magnetic field lines are targets of the circumferential shape of circular. Distribution of magnetic field lines in different directions will film a great relationship.
Coating machine manufacturers said, not only in the interaction mechanism magnetron sputtering magnetic and electric fields of work, multi-arc plated target ion source, a plasma source and so work under this principle. The difference is that the electric field direction, voltage and current magnitude only.

Vacuum Coaters wet coating technology and coating technology

Vacuum Coaters wet coating technology and coating technology
Membrane extensive selection of vacuum coating technology, you can control the thickness of the film and coating system functionality and performance of different films, can make a lot of new material with chemical and physical properties.
Wet coating technology is way past a coating that plating or electroplating, chemical reduction of the principles applied in the material deposited, this method will produce waste polluting the environment, in the past a lot of plating plant because of pollution problems have changed the coating process .
Vacuum coating system film coating technology, the film less susceptible to contamination, in a vacuum environment can be improved purity and compactness, no waste without pollution. Vacuum coating itself is contaminated, but the actual vacuum system will be used in organic coatings, it will also cause pollution, but compared to the wet plating technique, a lot less pollution, high efficiency vacuum coating technology has strong vitality, but it does not mean that vacuum coating technology can completely replace the traditional wet coating technology, and in the thickness of the film, the anti-aging still take advantage of the wet coating method, vacuum coating thin film coating system.
In addition, a solid layer is affected by the process and adhesion, either wet or vacuum coating technology coating technology, if the material surface is not clean and will affect the binding layer material.
With the development of science and technology, vacuum coating technology industries has become a means of improving product quality, low cost vacuum coating significant economic benefits so that more and more companies eager, China's production of vacuum coating machine has reached a considerable level, the system can be plated vacuum coating materials are also more and more, but the foreign equipment and contrast a little gap also exists for the development of vacuum technology to be improved.

Historical Development of vacuum coating technology

Historical Development of vacuum coating technology
In the film prepared in vacuo, crystalline coating system comprising a metal, semiconductor, insulator and other elemental or compound film. Although the chemical vapor deposition also uses vacuum, low pressure or vacuum plasma and other means, but generally refers to a physical vacuum deposition method for depositing a thin film. Vacuum coating has three forms, namely vapor deposition, sputtering and ion plating.
Vacuum coating technology is now beginning in the 1930s, forties and fifties began industrial applications, industrial mass production began in the 1980s, has made a wide range of applications in the electronics, aerospace, packaging, decoration, gilt printing and other industries. Vacuum coating means in a vacuum environment, a metal or metal compound vapor is deposited onto the surface of the material in the form of (usually non-metallic material), is a physical vapor deposition process. Because often the metal film coating, it is also called vacuum metallization.
Generalized vacuum coating further comprises a metal or non-metallic materials and other non-metallic surface of the vacuum vapor deposition polymer functional film. In all plating material to the plastic is most common, followed by, for paper coating. Relative to metals, ceramics, wood and other materials, plastics have sufficient sources of performance is easy to control, easy processing and other advantages, so a wide variety of plastic or other polymer materials as structural engineering decorative materials, widely used in automobiles, household appliances, household packaging, decorative and other industrial fields. However, the presence of surface hardness of plastic materials are mostly not high enough to look gorgeous, abrasion and low defects, such as the plastic surface layer deposited thin metal film can be given away plastic bright metallic appearance, suitable metal source also can greatly increase the wear resistance of the material surface, greatly expanded the scope and application of decorative plastic.
