Optically Coated Machine Description
What is optical thin film?
optical thin film refers to the components on the plating on a layer or multilayer film to change the light propagation characteristics, is basically by interference effect to achieve the effect.
The technological principle of the optical coating
How the membrane materials are plated to the parts?
The process of film formation.
After electron beam by 5 to 10 kv electric field acceleration, focus and hit for material surface evaporation, electron beam evaporation pass energy to stay material make it melt, electron beam rapid loss of energy.
The core of the electron beam evaporation system components: electron beam gun (hot cathode and plasma electrons)
Electron beam focusing method: electrostatic focusing and magnetic deflection is focused on the electron beam generated after, need to focus and allow it to direct him to be the surface of the evaporation materials.
E the principle of electron gun coating
