Chroma 58604 is a high-density, multifunctional, and temperature-controlled laser diode burn-in and reliability evaluation system.
Burn-in, Reliability & Lifetime Testing The Chroma 58604 is a module for high-density, multifunctional, and temperature-controlled laser diode burn-in and lifetime testing. Each module has up to 256 SMU channels and can supply current and measure voltage in various control modes as described below. Automatic Current Control Mode (ACC) In Automatic Current Control (ACC) mode, the control circuit supplies a preset current to each laser diode with high stability. Regardless of how the device's resistance and temperature change, the current is maintained constant throughout the testing period. The device voltage is recorded as a quality standard parameter. Auto Power Control Mode (APC) Using feedback signals from an optional external photodiode PCB, the control circuit can automatically adjust the laser diode current to maintain a constant feedback signal strength. This means that the optical output of the laser diode is kept constant throughout the testing period. The device's voltage and current are recorded as reference quality parameters.
