LEED Auger Electron Spectroscopy

 LEED Imaging software, LEED Data Acquisition Software and LEED Analysis Software. Fully integrated multitasking LEED IV Software.

The Low Energy Electron Diffraction experiment uses a beam of electrons of a well-defined low energy (typically in the range 20 – 200 eV) incident normally on the sample. The sample itself must be a single crystal with a well-ordered surface structure in order to generate a back-scattered electron diffraction pattern.

LEED Imaging Software

Real-time image display, Single or multiple frames capture.
Frame averaging and integration supported in all modes.
Dynamic adjustment of brightness and contrast.
Enhancement by background subtraction and contrast stretching (linear or non-linear).
Images exported as standard bitmaps.
Capture movies to hard disk (up to 10fps).
Movies can be analysed later using all features of Low Energy Electron Diffraction express, LEED Imaging or LEED Office.
