The AC-2S Series (AC-2S / AC-2S Pro α / AC-2S Pro β) use the principle of Photoemission Yield Spectroscopy in Air (PYSA) for quick easy measurement of work function and ionization potential; eliminating the need for measurements in a vacuum.
The AC-2 open counter counts the individual low intensity photoelectrons emitted when the sample surface is irradiated with weak low-energy UV light in air. Compared to conventional surface analysis in which high-energy X-rays are passed through the sample in a vacuum, this analysis technique causes minimal damage to the sample.
The AC Series is widely used around the world in universities and research facilities, with over 2,000 related articles published in scientific journals.
