Introduction
The ELL7 Linear Translation Stage is part of the Thorlabs series of resonant piezo motor circuits and bare
modules for OEM applications. The resonant piezo design of these motors offers fast response times and
precise positioning, and therefore they are particularly useful in scanning applications.
The high-speed digital signal processing (DSP) architecture supports a multi-drop serial communication
protocol, and a set of digital IO lines allows the user to control the movement and state manually by switching
the lines high (5V) or low (0V).
The stage is designed for closed loop applications requiring linear positioning over a 25 mm (0.984”) travel
range, with 0.5 µm of resolution. The module is powered via an external 5V power supply supplied in the kit.
A hand-held controller is supplied with the ELL7K evaluation kit to allow homing and manual jogging and/or
positioning. The unit can also be driven remotely via PC-based software, downloaded from
A compatible USB driver and source code are included in the software download package.
