This Ultra High Vacuum Kelvin Probe Corner Cube Training System includes a UHV head unit, tip amplifier (located at the mounting port), digital control unit (DCU) and host PC. The tip can be retracted 50 mm from the sample and approaches normal to the sample. The system comes complete with a user manual, which includes an introduction to work function measurements and a detailed description of the system software, including examples.

The UHVKP corner cube training system comprises of an optical table, camera/camera monitor, DCU, PC, monitor, oscilloscope and system software. The software features user digital control of probe amplitude, probe frequency, mean spacing, tip potential. Automatic measurement of Kelvin Probe signal, work function and work function averaging, automatic control of tip to sample mean spacing. Additional signal channel available. Export of data to Excel compatible spreadsheets.
