Spin analysis

FOCUS is the supplier of state-of-the-art electron spin detectors since 1991 already.

Our recent standard spin detector is the
FOCUS FERRUM detector (left) what is based on very low electron energy diffraction (VLEED) on a thin magnetized iron layer.

A versatile and compact instrument to be used for spin polarized electron spectroscopy is our EasySPIN (right), a combination of the FERRUM with an electron energy analyzer.

The SEMPA detector (left) we make for spin polarized imaging with a scanning electron (UHV) microscope. It is using the FOCUS SPLEED.

FOCUS SPLEED has been over years our standard and already widely spread spin detector. It is based on low energy electron scattering on a clean tungsten single crystal.
