Optical coating vacuum chamber
Optical coating vacuum chamber is composed of thin film layers, which can improve the reflection performance or transmittance of the optical system through interference effect. There are various processing types of optical coating vacuum cavity
Optical coating vacuum chamber is composed of thin film layers, which can improve the reflection performance or transmittance of optical system through interference effect. The performance of optical coating depends on different layer interface, layer number and thickness refractive index of individual layer. Common coating types of precision optics include: filter film, spectroscope film, high reflection film and antireflection film (AR)

Antireflective coatings are used in high refractive index optics to increase light flux and reduce ghost images. High reflection coatings are designed to reflect a large extent over a wide range of wavelengths or single wavelengths. Spectroscopic membranes divide incident light into known transmitted and reflected light outputs. Filters are used in a large number of industrial applications, and transmit, reflect, absorb or attenuate light at specific wavelengths
The anode layer ion source applies magnetic field in a narrow annular gap to ionize the working gas and shoot it to the workpiece under the action of anode. The anode layer ion source can be made very long, especially suitable for coating large workpieces, such as building glass. The ion current of the anode layer ion source is also large, but its ion current is divergent and the energy level distribution is too wide, Decorative parts. Not many applications in optical coating
Although there are many types of ion sources, the purpose is nothing more than on-line cleaning, modulating to increase the energy of reaction gas and improving the energy distribution of the plated surface. If the thickness of the wear-resistant layer of the plating tool is large, the uniformity of the film thickness is not required, The ion source with larger ion current and higher energy level can be used, such as hall ion source or anode layer ion source
Hall ion source is the anode plasma the process gas under the cooperation of a strong axial magnetic field. The strong imbalance of the axial magnetic field separates the gas ions and forms ion beam. Because of the strong effect of the axial magnetic field, the ion beam of hall ion source needs to supplement electrons to neutralize the ion current
