The BPC203 Piezo Controller is an apt™, three-channel, high power (75 V, 500 mA), benchtop piezo controllers for open- and closed-loop nanometer position control. It has been designed to drive the full range of open- and closed-loop piezo equipped nano-positioning actuators and stages offered by Thorlabs. In addition, flexible software settings make this unit highly configurable and therefore suitable for driving a wide range of piezo elements in third party products. A waveform generation capability combined with triggering outputs makes this unit particularly suitable for piezo scanning applications.

Manual controls are located on the front face of the unit to allow manual adjustment of the piezo position using the digitally encoded adjustment pot. The display is easy to read and can be set to show either applied voltage or position in microns. Open or closed loop control and zeroing of the piezo can also be selected from the front panel.

USB connectivity provides easy plug-and-play" PC operation – multiple units can be connected to a single PC via standard USB hub technology for multi-axis motion control applications. Coupling this with the very user-friendly apt™ software allows the user to very quickly get up and running in a short period of time – for example all relevant operating parameters are set automatically for Thorlabs piezo actuator products. Advanced custom motion control applications and sequences are also possible using the extensive ActiveX® programming environment.
