The Electron Microscope Unit (EMU) provides advice and centralised training to both academic staff and research students in the aspects of electron microscopy for the entire University. The principal users of the EMU facilities come from the Faculties of Engineering, Medicine and Science. The unit manages three transmission electron microscopes, three scanning electron microscopes and one dual-beam focus ion beam system. Supporting these equipments are all the facilities necessary for the sample preparation, as well as photographic printing and on-line computing services all of which are housed in the University Pathology Building in the Queen Mary Hospital Compound.
