| A.P.E. Research instrument is a
versatile Scanning Tunneling Microscope, STM, capable of scanning samples
of almost any size. It can operate in UHV and in air. It is provided with a simple-to-use acquisition software and with tools for image analysis during acquisition sessions. Custom models can be provides suited to the research needs. |
