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 This constant current source is suitable for: Electrically tunable lenses LEDs Laser diodes
