The Lens Driver 4 offers a simple yet precise way to control Optotune’s electrically tunable lenses, in particular the EL-6-18 and EL-10-30 series. 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 available). The driver comes with free software and can be used as a standalone solution or integrated into OEM designs. As a compact USB-powered current source, it also serves for driving LEDs or laser diodes.

OEM driver CL190 & CL191 by Gardasoft
Customers looking for a compact lens driver to integrate into their design will find an ideal solution with Gardasoft's CL190 & CL191 drivers. These drivers are compatible with all Optotune lenses and offer similar features to the TR-CL180 above. The controller provides +/- 250mA and can interface through UART, I2C or 0-10V analog. The CL191 (shown on the right) can be purchased as a completely tested miniature board including a connector for the lens FPC cable. The CL190 is an even smaller design module that can be copy/pasted into the user’s PCB design.EL-E-OF-A Lens Driver for EL-10-42-OF with Analog Interface (0-5V)
The EL-E-OF-A enables the control of the EL-10-42-OF lens module via an analog voltage signal. Several digital signals are available for status verification. The electronics essentially provides an analog-to-digital stage to read the control and set voltage signal, digital processing with an implemented PID-loop and current sources to drive the lens and the heater unit. The board is optimized for OEM-integration in laser marking systems and therefore comes without housing.
Main features:
- Analog control voltage from 0 to 5 V (ADC resolution 16 bit
- Sampling rate 1.1 kHz
- Lens driving current ranging from 0 to 300 m
- Integrated optical feedback (OF) control
- JTAG or USB interface for firmware update
SCAPS Optotune-DSD Lens Driver for EL-10-42-OF with Digital Interface (XY2-100)
.jpg)
Optotune-DSD is an FPGA-based digital controller which is used for the control of the EL-10-42-OF lens module. The board is composed of two layers for which the top one is Digital Servo Interface (DSI-1-O16) and the bottom one is Digital Servo Controller (DSC-1). The board is particularly designed and optimized for OEM-integration in 3D laser marking systems.
Main features:
- Pulse-width modulation (PWM) based lens control
- Automatic tuning for the lens
- Tracking delay of <1ms
- Heater control unit
- XY2-100 and bi-directional XY-SCAPS interface
- Marking speed up to 8000 mm/s for a 45-degree hatching job
