Cotest has independently developed this semi-automated test system to address narrow-pulse performance testing requirements for VCSEL packaged devices.The system integrates a stable automated motion platform with multi-material compatibility, enabling testing across various package dimensions. It supports adaptable photoelectric testing configurations,including:LIV testing under narrow-pulse driving mode (current/voltage/optical power time-domain waveform analysis);Far-field optical characterization;Electrical performance testing of integrated Zener diodes.
