The WLD33ND-3A is a general purpose laser diode driver that maintains precision laser diode current or stable photodiode current using electronics that are compatible with any laser diode type. It delays and slowly ramps the current for maximum protection. Supply up to 3A to your laser diode from a single +5V power source. It is widely used in electro-optic qualification, Raman spectroscopy, medical diagnostic equipment, range finders, eye-safe atmospheric lidar and on research benches.
