Introduction of vacuum coating equipment manufacturers to the performance and application of optical vacuum coating machines







According to the optical vacuum coating machine manufacturers, the optical vacuum coating machine also has the same decorative requirements for mobile phones, digital products and pipes. Optical coatings are available in a variety of colors, shades, and metallic sheens from base electroplating films and clear dielectric multilayer films. With silk screen printing, thermal transfer printing, laser engraving and drawing technology, it can obtain dazzling luster in various shades. Optical coating can enhance the stereoscopic vision of stripes and patterns, and can also improve the performance of vacuum coating and reduce material consumption.



Optical vacuum coating machine coating refers to the process of coating one (or multiple layers) of metal (or dielectric) films on the surface of optical parts. The purpose of electroplating on the surface of optical parts is to reduce or increase the requirements of light reflection, beam splitting, color separation, filtering, polarization, etc. Commonly used coating methods are vacuum coating (one of physical coatings) and chemical coating.


    Optical vacuum coating machine manufacturers introduce the principle that optical vacuum coating machines are widely used in thin film optics. The common method of optical thin film technology is to coat a thin film on a glass substrate by vacuum sputtering, which is usually used to control the reflectivity and transmittance of the substrate to the incident beam to meet various needs. In order to eliminate the reflection loss on the surface of optical parts and improve the imaging quality, one or more transparent dielectric films are coated, which are called reflective films or reflective films.


    With the development of laser technology, the requirements for the reflectivity and transmittance of coatings have changed, which has promoted the development of multilayer high-reflection coatings and broadband anti-reflection coatings. In order to meet various application requirements, high-reflection films are used to make polarized reflection films, color spectrum films, cold light films, interference filters, etc. After electroplating on the surface of optical parts, the light is reflected and transmitted many times in the film layer, forming multi-beam interference, controlling the refractive index and thickness of the film layer, and obtaining different intensity distributions are the basic principles of interference coating.


The optical vacuum coating machine has a wide range of applications. In addition to the 3C industry, it is also suitable for adding AF and AS coatings to the decorative and functional films of plastic or metal parts such as electrical appliances, sanitary ware, and medical to improve the finish. Optical vacuum coating machine can coat various film systems, such as short-wave pass, long-wave pass, anti-reflection film, reflective film, filter film, beam splitter film, dielectric film, high reflection film, bandpass film, color reflection film, etc.


     Finally, the optical vacuum coating machine manufacturer also introduced that the coating machine is equipped with different evaporation sources, electron guns, ion sources and coating thickness gauges. Super hard surface.
