The LDD100 is a fast pulsed current source for
driving laser diodes and high power LEDs.
We offer this instrument with various end stages with current ranges from 1A to 400A. The graphical user interface is clear and intuitive to use.
The LDD100 employs a digitally programmable analogue end stage for flexible and accurate current control. Currents of up to 400A with pulse durations of 50ns to 3s are generated with rise and fall times of 50ns (F-version) or 600ns (XL-version) – essentially without overshoot. Due to the flexibility in setup and control, the LDD100 is practical for many laboratory applications. For automated measurements, the unit may be directly controlled via the USB interface. Alternatively, all parameters may be input via the graphical software or via the integrated keypad and OLED display.
FIELDS OF APPLICATION:
Applications include laser diode characterization (LIV measurements, etc.), general lab use and for OEMs. The LDD100 from Artifex Engineering generates fast and very square current pulses and is very simple to operate. Artifex Engineering supports this product with a custom strip line configurations service.

Our Software Development Kit
The SDK package is a fixed, free component when purchasing a device.
It comes with the source code of the application program (in VB.net) and a LabView VI with the basic functions of the instrument. A description of the communication with the devices and a list of the commands used is also included.
For some devices (currently LDD100, LIV120 in preparation) there is a dll file (library file) with documentation and exemplary applications in VB.net and LabView.
