Description Reviews

Solver Nano is the best choice for scientists who are need a single instrument that is an affordable, robust, user-friendly and professional tool.

Compact desktop AFM/STM for both education and science

Full set of AFM/STM modes

High AFM/STM performance

Closed-loop Scanner

Applications

Solver Nano is designed by the NT-MDT SI team that also created High Performance Systems like NTEGRA, NEXT II and NTEGRA Spectra II which have been proven in the scientific community through many key publications.

Solver Nano is equipped with a professional 100 micron CL (closed loop XYZ) piezotube scanner with low noise capacitance sensors. Capacitance sensors in comparison with strain gauge and optical sensors have lower noise and higher speed in the feedback signal. The CL scanner is controlled by a professional workstation and software.

These capabilities enable all of the basic AFM techniques in compact SPM design.

Because the SolverNano can be employed in diverse areas of research as AFM tool, several research examples are shown below:

Polymers
Bio objects
Carbon Materials

Configuration and experimental setup:

Solver Nano with AFM head.
CL 100 um piezotube scanner. CL enabled.
Digital controller.
Active vibration isolation.
Results from intermittent contact mode (topography, phase, and amplitude image).
