STM Controller

ZLS1000 High-Performance Control System  
Integrating data acquisition, feedback control, and high-voltage scan driving

PXIe Architecture | NI FPGA Programmable | 4-Channel High-Voltage Output

STM Controller is a high-performance scanning tunneling microscope control system independently developed by ZEPTOOLS. Built on a standardized PXIe platform, it integrates high-precision signal acquisition, real-time feedback control, and high-voltage piezoelectric driving into one unit, providing a stable and reliable hardware foundation for atomic-scale resolution imaging and spectroscopic measurements.

The system supports multi-channel synchronous acquisition and bidirectional forward/reverse scanning, balancing imaging quality and scanning efficiency. Its high-voltage output can drive large-travel cryogenic piezoelectric ceramics, readily handling extreme experimental environments such as low temperatures and strong magnetic fields. It is widely used in frontier research fields such as surface science, two-dimensional materials, and nanoscale characterization.
