The Thorlabs MDT693 is a precision, low-noise, low-drift, high voltage 3-channel controller for piezo actuators. The MDT693 provides both manual and external control of the piezo drive voltages. The MDT693 is an ideal driver for use with Thorlabs Piezo Actuators including the PE4, KC1PZ, MDT631 and the AE-series piezo elements. Typical applications include remote alignment of single-mode fiber couplers, high-resolution translation, microscopy, remote positioning, etc.
Each of the three piezo drive voltages can be controlled independently. Precision 10-turn potentiometers on the front panel allow for precise manual setting of the outputs over the full operating range. This allows hands-off control of the piezo translators to take full advantage of the inherently high resolution of the piezo element.
The drive voltage can also be controlled externally by applying an analog voltage (from 0 to 10 V) to the front panel BNC inputs or remotely controlled by a computer terminal through an RS-232 interface. This voltage is multiplied by a gain of 15 V/V and summed with the manual control voltage.
