SF6 is the series of high power, compact OEM constant current laser diode drivers. Unique laser driver circuit solutions allows to achieve high efficiency (up to 97%) and high power density. Aluminum base plate provides effective remove heat from laser diode driver module with the water or air cooling. Laser current driver have generous amount of protection features for laser diode safety operating. The main fields of application for high power laser drivers SF6 is laser marking, welding, soldering, and cutting applications, medical equipment, laser measurement equipment, spectrometers, lidar, range finders and laboratory test set-ups.
