ASC500
fully digital SPM controller with xy-scan generator and z feedback control, phase-locked loop (PLL)
The ASC500 is a modular and flexible digital SPM controller which combines state-of-the-art hardware with innovative software architecture,
offering superior performance and unprecedented variety of control
concepts. It was developed with the goal to never be the limiting factor
in any scanning probe microscopy (SPM) experiment.
All desirable functions and high-end specifications for conducting
the experiment of your choice in AFM, MFM, KPFM, PRFM, CFM, SHPM,
SNOM, STM, and many more measurement techniques are available. The
ASC500 features optional closed loop functionality, fully supporting
attocube’s FPS interferometric sensors.

„The attocube low-temperature AFM is a versatile instrument which provides
a good balance between the flexibility of a user-built setup and the reliability and ease of installation of a commercial instrument. I particularly recommend the ASC500 SPM controller, as it allows for advanced control modes
such as phase lock loop (PLL), but still provides a great deal of flexibility in
configuration, and ready access to all signals.“
“Working with an evolving self-developed technique means our needs
constantly and rapidly change. It is thus very important for us to have a
controller with high flexibility and versatility. The ASC500 allows us to easily
and smoothly adjust our measurement scheme to meet the needs of the
moment. It has proven to be a powerful tool for scanning probe microscopy”
