IEF / ToF PEEM
The Imaging Energy Filter (IEF) is operated like a retarding field analyser upon conserving the full image quality at the same time. From this it acts as an imaging high pass filter. It represents a compact and versatile energy filter for all applications with good photoelectron yield and at low binding energies, with an energy resolution of <50 meV. For time resolved studies the Time-of-Flight (TOF/DLD) PEEM combined with a pulsed laser or synchrotron beam line enables time resolved imaging with an overall time resolution down to 180 ps used for parallel energy filtering by converting the time slices into energy slices, with an energy resolution <50 meV.
