Active vibration isolation table

Isostage 300

The Isostage 300 is an active vibration isolation table that protects all your measurements against disturbances caused by building floor vibrations. Optical tables or heavy granite tables do provide substantial damping of building vibrations. However they provide only passive damping while active vibration isolation tables are superior by measuring vibrations and actively counter act them. As a result they have become the industry standard in applications requiring lowest noise levels as AFM and STM do.

The Isostage 300 is compatible with the FlexAFM, integrated in the CoreAFM and adapters are available for the NaioAFM and NaioSTM. A special feature is, that it is equipped with holes to directly mount Nanosurf stages, so that they are fixed in position. Another unique feature is the center hole of the Isostage. This space directly under the tip of the AFM allows for tall samples, a variety of samples holders and a much more open access from the bottom.

The control unit comes with another unique feature: the Spike-Guard. It eliminates glitches during AFM imaging when coupled with a Nanosurf C3000 AFM controller. Although any vibration isolation system will compensate for regular environmental vibrations, glitches can still occur when disturbances become too severe (e.g. when someone accidentally hits the table that hosts your AFM or the closing of a door). Having such a glitch in your almost finished AFM image meant - measure again. Not so with Spike-Guard. It detects such anomalies and directs the AFM software and controller to automatically rescan the line for a disturbance-free image. You won’t find this functionality anywhere else!
