Scanning Kelvin Probes System

 

      System Description                                      

Our large range of Scanning Kelvin Probes gives the user full access to 2D and 3D Work Function plots of samples ranging

in size from 5mm to 300mm. With Work Function resolution

at less than 3meV, and the resolution of the 3-axis scanning stages as low as 317.5nm, the Scanning Kelvin Probe gives reliable, repeatable measurements.

 

A high performance Faraday and optical enclosure shields all of our scanning systems from unwanted fast changing environmental conditions, electromagnetic interference and providing the perfect platform for our Photoemission and Surface Photovoltage add-on modules.
