STM Head
STM Head with tip holder.
The Head houses low corrent preaplifier with  1·109 V/A gain that make possible to get images from 2pA to 2nA. Other preamplifiers with differents gain are optional on request.

SPMCU-T
SPM Control Unit
SPM Control Unit and PC (equipped with a multi input-output board)  drives the scanner, data acquisition and sample motion.
Tip to sample distance is controlled by ultra-low noise analog feedback, digitally driven by PC.
Scan generator is controlled by software, xyz axis are driven by compound DAC with resolution better than 20 bit.
High speed and temporal precision are provided by hardware timing.

HVA3-T Unit
High Voltage Amplifier
HVA is an amplifier module projected to drive A-100 Heads.

Computer and Acq. Board
Windows XP/Vista operating system; Pentium Core 2 Duo, 1GB/2GB DDR2 SDRAM, 160 GB HDD, CD R/RW, mouse, keyboard; 17 inch LCD monitor. Acquisition board and interface.

Acquisition  software
Software runs under Windows and is composed of a multi-window applications for instrument control and data acquisition. The software comes equipped with simple filters for immediate analysis of acquired images. The software controls all the parameters of the instrument.

Accessories
AFM Tool
AFM Head is suitable for Contact Mode, Non Contact Mode and Semi-Contact Mode.
AFM Head with holder for commercial cantilevers. The holder can be removed to easy mount cantilevers. The head also houses laser, fotodiode sensor with preamplifier.
