| Frequently Asked Questions |
What is the compatibility with different microscopes?
The ActivResonance ControllerTM has been tested with the DI/Veeco Nanoscope IIITM,
Nanoscope IIIaTM and Nanoscope IVTM controllers with a phase extender box and the Molecular Imaging PicoSPMTM.
Due to the ease of signal access, it should be possible to adapt it to work with
most commercial AFM systems. We are working with present users to provide an
ActivResonance Control solution for most commercial AFM systems. If you have a
microscope you wish to use it with, please contact us and we will endeavour to
implement a working system.
What is the frequency range?
The ActivResonance Controller has been optimized for a frequency range between 1 and 400 kHz.
Can the ActivResonance Controller be used for imaging in liquids and in air?
Yes,
the ARC comes in two versions.
INF-102A For operating in air only (1-400kHz) environments
and
INF-102AL For operating in air (1-400kHz) and liquid (1-50kHz)
environments.
What is the difference between the Infinitesima ActivResonance Controller and the Nanoanalytics Q Box?
Our ActivResonance Controller has some extra
electronics that allow it to be used for imaging in liquid. As far as we are
aware there are no images using other Q boxes or Q enhancements, such as that in
the Nanoscope IVTM, showing Q technology working in liquid to
enhance imaging.
What is the connectivity and accessibility of signals?
As well as the DI/Veeco D-connector, there are
three BNCs on the back of the ActivResonance Controller which allow access to
the major signals. There is also access to monitor an additional four signals at
different stages in the ActivResonance Controller circuit on the front panel, to
enable the maximum amount of control and information for the academic user.
Can the ActivResonance Controller be used to reduce the Q?
Yes, the unit can implement a phase shift from 0-360°.
How does
it interface with commercial AFMs?
With
the Nanoscope III controllers, the D-connector from the microscope
plugs into the back of the ActivResonance Controller, and
a D-connector terminated extension cable is taken from the
ActivResonance Controller to the extender. With the MI PicoSPM,
three BNC cables connect the MAC box to the ActivResonance
Controller. A switch is used to change the configuration of
the ActivResonance Controller to suit the microscope. Other
microscopes will be implemented using the BNC connectors.
