To support experiments carried out at the Microscopy beamlines, we have several visible light microscopes available for both inside and general users. Some of these instruments (in particular the Leica microscope) require a certain level of training before they can be used, so if you anticipate to require the use of one of these instrumentsit would be best to check with either beamline contacts or the contact person listed below on their availability, and training.
