Solver Pro




Solver PRO-M is a powerful and well-designed universal scientific SPM applicable to almost all areas that SPM can ever be exploited in. Some features make it unique in terms of electronics capability, probe movement precise measurements, and optical system convenience.

The Solver PRO-M model has been suited to be driven by the new-generation controller. It has been designed to incorporate modern achievements in microelectronics. Elegant module architecture and many new design solutions allowed creating one of the most powerful "brain" that SPM ever possessed. It contains more than 10 000 components from the world-best manufacturers as Analog Devices, Burr Brown etc.

Product Features

Very important feature is that the new controller is perfectly suited to work with high frequencies (up to 5 MHz). Thus it is compatible with high frequency cantilevers that can be required to obtain the best quality images. High frequency compliance measurements are also important to perform AFAM (Atomic Force Acoustic Microscopy) – NT-MDT unique microscopy technique for imaging samples with differences in local stiffness. The controller is also designed to process capacitive sensors feed-back signal providing precision scanning.
