Electronic test loads are very useful when testing laser diode driver. Many simple laser diode drivers do not have a readout of the current setpoint or require a load in order to set the current to the correct value. A good test load acts as a robust load for your laser diode driver without risking an expensive laser diode.

Electronic test loads for laser diode drivers a constant voltage test loads. The most simple test loads are normal rectifying diodes in series to emulate a laser diode with a certain voltage drop. More complicated test loads have an adjustable voltage setpoint and a readout for the current. Bluefan.nl can make test loads to customer's specifications.
