Optical Thin-films Deposition Machines

详情

The principle of vacuum optical thin-films deposition machine(electron gun)is as follows: High energy electron beam generated by electron source bombard the coating material in the crucible under the effect of magnetic field,and the material is dissolved and evapored to film through high temperature produced by transformation from kinetic energy into thermal energy. The charged particles(generally used gas cation) bombard the object ,thus atom on the
surface of object escaped from the precursor.The special film coated on the surface of solid has characteristic of high wear resistance、corrosion resistance、high temperature resistance、antioxidant、radiation protection、conduction、magnetic conductivity、insulation、decoration and so on.It can increase productivity、extend life cycle、save energy,and acquire remarkable technological and economic benefits.

Vacuum optical(electron beam) coating machine can coat anti-reflection film、reflective film、filter film、beam-splitting film、bandpass membrane、dielectric film、high reflectivity film、color reflection film and so on. The membrane system range from 0 to *9 layer.This machine has a wide range of applications for such field as auto reflective glass、telescope、spectacle lens、optical lens、luminescent cup and so on.If equipped with different evaporation source、electron gun、 ionization source and film thickness gauge, It used for vapor deposition on the surface of metal、oxides、compound and other high melting point materials.It can also coat super hard film on the surface of glass.
