Ion Source

OIS-Three/OIS-Three Plus

RF Ion Source

OIS-Three/OIS-Three Plus has an incomparable high power beam to any other ion beam assisted deposition systems.

Uniform irradiation covers an entire dome with 1600 in diameter.

OIS-Three/OIS-Three Plus is most suitable for mass production of sophisticated optical filters when equipped with OTFC-1800.

Newly developed grid has long life.
Long life and less contamination.
Higher uniformity of ion density with a wide coverage over a dome with 1600mm in diameter.
Great stability and non-stop operation for longer hours.
