Scanning Kelvin Probe System
(3D 켈빈 프로브)
Description | |||||||
---|---|---|---|---|---|---|---|
Our large range of Scanning Kelvin Probes give the user full access to 2D and 3D work function plots of samples ranging in size from 50 mm to 350 mm. With work function resolution of 1-3 meV, and the spatial resolution of the probe tip diameter, the Scanning Kelvin Probe gives reliable, repeatable measurements for work function (φ), contact potential dierence (CPD) and Volta potential (Δψ) measurements.
Effects of corrosion can be measured across a surface with high precision e.g. coating uniformity and performance. A Faraday and optical enclosure shields all of our scanning systems from unwanted fast changing environmental conditions, electromagnetic interference and provides the perfect platform for our Ambient Pressure Photoemission Spectroscopy (APS) and Surface Photovoltage add-on modules. |
