PAGE 386 Accessories optional items for the attoCONTROL product line Kelvin Probe Force Microscopy Upgrade Via an optional software upgrade, the ASC500 (Hardware Version v2 or higher) can be used for Kelvin Probe Force Microscopy. The module allows measurements of the surface contact potential difference (CPD) in a dual pass mode: during the first line, the topography signal is recorded, which serves as a reference base line during the data acquisition in the second line, so that topography features are cancelled out.
