Pulsed Laser Diode Test System with Remote Test Head

main product photo

The Model 2520 Pulsed Laser Diode Test System is an integrated, synchronised system for testing laser diodes early in the manufacturing process, when proper temperature control cannot be easily achieved. The Model 2520 provides all sourcing and measurement capabilities needed for pulsed and continuous LIV (light-currentvoltage) testing of laser diodes in one compact, half-rack instrument.

The tight synchronisation of source and measure capabilities ensures high measurement accuracy, even when testing with pulse widths as short as 500ns.
