Opto Engineering® offers controllers available as accessories to precisely adjust the optical power of liquid lens modules integrated in the Opto Engineering products.

The lens drivers form the ELDV series offer a simple yet precise way to control the electrically tunable lenses integrated in the OE products. Communication with the driver follows an open simple serial protocol, which can be implemented in any programming language on Windows or Linux (C#, Labview and Python source code is available). The driver comes with free software and can be used as a standalone solution or integrated into OEM designs.
