Burn-in, Reliability & Life Test
The Chroma 58604 is a high density, multifunction, and temperature controlled module based system for laser diode burn-in and lifetime tests. Each module has up to 256 SMU channels which can source current and measure voltage in various control modes as described below. The system can accommodate 7 modules for a total of 1792 SMU channels.

Auto Current Control Mode (ACC)
In auto current control (ACC) mode, the control circuit will provide the preset current to each laser diode with high stability. Even with fluctuations in device resistance and temperature, the current will be kept constant over the test period. The device voltage will be recorded as a quality reference parameter.

Auto Power Control Mode (APC)
With feedback signal from the optional external Photo Diode PCB or the onboard Monitor Photodiode (MPD), the control circuit can adjust the laser diode current automatically to keep a constant optical power output over the test period. The device voltage and current are recorded as quality parameters for reference.
