    • Precision constant current laser control bench     


    The LaserBench is a constant current laser diode driver for powering 10/14-pin butterfly laser diode modules for applications, which require high precision low ripple constant current regulation.

    The driver circuitry operates from a single 12Vdc power source. The driver supplies a bidirectional proportional-integral-derivative (PID) thermoelectric cooler controller (TEC) with current capability of 4A and voltage capability of 4V. Maximum TEC current is regulated by user.

    The main parameters of LaserBench (output current, temperature set, maximum TEC current, monitor photodiode signal) are controlled by touch screen.

    The LaserBench can control multiple LD-PD laser controller board via RS232 interface.
