Product description:

The STM Aarhus with ultimate atomic performance allows scientists to observe nanometer scale processes on surfaces.
The minaturized design with a small mechanical loop between tip and surface results in an extreme stability, unique in the STM market. Fast scan rates are achieved by high resonant frequencies of this scanner head design. The STM 150 Aarhus is equipped with a fast approach mechanism for full approach speeds of more than 1 mm/min. The tip may be cleaned by parallel ion beam etching, field emission or short voltage pulses with no necessity for tip exchange as in other STMs.
The STM Aarhus was designed by Professors Flemming Besenbacher, Erik Lægsgaard, and Ivan Stensgaard at the University of Aarhus, Denmark, and is being exclusively produced and marketed by SPECS GmbH.
