Lens driver 4 and 4i
Lens Drivers 4 and 4i offer a simple yet precise way to control Optotune’s electrically tunable lenses, in particular the E-3-10, EL-10-30, EL-12-30 and EL-16-40 series. Communication follows an open serial protocol, which can be implemented in any programming language on Windows or Linux (C#, Labview and Python source code are available). The controller 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.
Main features:
Current control from -290 to +290 mA in 0.07mA steps
Drive frequencies from 0.25 to 2000 Hz (rectangular, triangular, or sinusoidal)
I2C sensor read-out e.g. for temperature compensation (“Focal Power Mode”)
USB powered (5V)
UART control option available
Software for Windows 7,8 & 10
Available with plastic, steel, or without housing
