Controller

The Piezoconcept controller includes ultra low noise and highly linear electronics, closed-loop control (PID) leading to a movement free of positioning errors. 

 

Our controller offers three different ways of control that can be used simultaneaously :

• Voltage control : an analogue input (BNC) located on the front panel of the controller allows to control the position of the stage by using voltage. Different ranges are possible : (0-10V, -5V/+5V, or -10V/+10V)
• As an option, the USB interface allows to control the position of the stage by using a computer. The USB connector is located on the front panel of the 1-axis controller or on the back panel of the 2/3 axis controller. It comes with 4 TTL outputs ( that can be configured also as inputs)
• As an option, it is also possible to control the position manually by using a 10-turns potentiometer located on the front panel. This option comes as standard on the 1-axis controller.

	2 axis Controller
	3 axis Controller

 

 

Main characteristics of the USB interface :

– Four channels DAC : depending on the number of axis, one, two or three channels are used. Upon request, the remaining DAC(s) can be used to send a command voltage (through a BNC) to an external device.

– Four channels  ADC : depending on the number of axis, one, two or three channels are used. Upon request, the remaining ADC(s) can be used to acquire a signal between 0 and 10V (through a BNC) from an external device.

– Four TTL outputs (through BNC). Upon request, those can be also configured as inputs

– Computer waveform generation and position data logging with internal memory for up to 65000 positions

Advanced scanning mode 

Our USB interface offers full scanning functionnalities  :

– SWIFT mode : 1D Line scan, 2D Image scan, 3D Volume scan

– FRAP mode : With this mode, you can get the system to scan over the area of a polygon. As an example, in Micromanager, you can draw regions of interest on an image. You can then control the piezostage through the MM device adapter.

– Arbitrary 3D laser writing mode : This mode is ideal to scribe a photoreactive material.
