Laser Diode Driver
LDD100
Artifex Engineering GmbH & Co. KG
The LDD100 employs a digitally programmable analogue end stage for flexible and accurate current control. Currents of up to 600A with pulse durations of 50ns to 3s are generated with rise and fall times of 70ns (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.
