A simple method is proposed to improve the depth resolution of a conventional X‐ray confocal microscopy system by adding a thin wire close to the sample surface and upstream of the polycapillary in the exit channel. A depth resolution of around 10 μm is easily obtained. The detection efficiency is i...
