Abstract

We have developed and brought into operation a new type of scanning UV photoelectron microscope. It is based on an ellipsoidal mirror which focuses the output capillary of a laboratory rare-gas discharge lamp onto the sample. Focus diameters down to 1.5 μm can be routinely achieved. At this spatial resolution angle-resolved (normal emission) electron distribution curves may be taken at energy resolutions selectable down to below 0.1 eV with sufficient intensity. We report on details of the new microscope and present several examples of its performance for microspectroscopy and energy-resolved imaging.
