ELECTRON BEAM SOURCE THIN FILM DEPOSITION CONTROL

Univac electron beam gun applies an electron beam vertically onto the evaporant surface by electric and magnetic field. The gun provides uniform
energy distribution, making it ideally suited for deposition of oxides as well as sublimation material. And this gun holds multiple crucibles, it is Thin Film Deposition Controllers
used as a general purpose electron beam gun for producing optical multi-layer films.

Various Electron Beam Module and Crucibles (6, 8, 12, 24 pockets)

OMD-1000

OMD-1000 has been developed to monitor the film thickness on the substrate in the coating process.
Chopped light reflects on the thin film and then the change of reflection is observed. It enables to control
each layer precisely and to produce excellent optical components.

IL541 / 550 / 850
The IL550 Series of optical monitors are designed to be fitted to your coating chamber and integrated into
your coating process. And it provide real-time endpoint capability for a wide range of precision optical
coating applications ranging from 300nm to beyond 12 microns.
