A table-top micro beam XRF spectrometer based on the properties of capillary optics has been realised. The system is equipped with two beam lines obtained by microcapillary collimators with inner diameter of 400μm and 100μm respectively. The X-ray probe has been characterised in terms of spectral monocromaticity, intensity gain, lateral resolution, beam divergence and intensity. Preliminary applications on ancient layered glasses and plaster detachment stratigraphies are presented. The advantage of the coupling of the microcapillary collimators with an already installed PIXE induced-XRF source is also discussed.
