The optical pvd coating machine feels out of reach, but now the optical coating machine is very widely used in the market, and has also been recognized and loved by many manufacturers. Today, the editor of Huicheng will explain to you the knowledge related to optical coating. Optical film is the most important part of modern optical and optoelectronic systems. It has become a core component in high-tech and industrial fields such as optical communication, optical display, laser processing, and laser nuclear fusion. Its technological breakthroughs often become the acceleration of modern optical and optoelectronic systems. main cause of development. The technical performance and reliability of optical films directly affect the performance, reliability and cost of the application system. With the continuous development of the industry, precision optical systems have higher and higher requirements for the spectral control capability and precision of optical thin films, while consumer electronics demand for optical thin film devices emphasizes the large-scale mass production and the ease of use and comfort of the general public. .

 Optical coating technology has achieved rapid development in the past few decades, from boat evaporation, electron beam thermal evaporation and its ion beam assisted deposition technology to ion beam sputtering and magnetron sputtering technology. In recent years, the main technologies in the field of deposition technology and equipment are as follows:
1. Technology and equipment of graded index structured thin films:
Graded-index structure thin film technology and equipment: A lot of research work has confirmed that the Rugate interface-free thin film structure and the quasi-Rugate multi-refractive index thin film structure can design very complex spectra by enhancing the distribution of the refractive index in the film thickness direction. performance, (partially) eliminated
The improved film interface features (partially) eliminates interface effects, such as the higher density of absorption centers and scattering of electromagnetic waves at the interface than inside the film, and can also increase the mechanical stability of the film.
2. Magnetron sputtering optical pvd coating machine
Represented by Leybold Helios and Shincron RAS, magnetron sputtering technology and equipment occupy an increasing share in the field of precision optics and consumer optoelectronic thin films. The magnetron sputtering thin film deposition process is easy to control, the particle energy is high, and the obtained thin film structure is dense and stable.
3. Intermittent direct light control:
Intermittent direct light control: Represented by the OMS5000 system of Leybold Optics, intermittent signal acquisition systems are increasingly used in the optical coating process to directly monitor the coating process product sheets. Compared with indirect light control and crystal control systems, the intermittent direct light control system is beneficial to reduce the film thickness distribution error on the actual product, which can further improve the product yield and reduce the process debugging time.
The above is a selection of optical coating related knowledge from Huicheng Xiaobian. I hope it can help friends who are interested in optical pvd coating machine coating knowledge. Later, I will provide more knowledge about optical pvd coating machine coating for everyone to learn and reference.
