Automated end-face inspection equipment for TOSA/ROSA, single-fiber FA assemblies, and other single-core optical fiber devices. Equipped with an optical microscopic imaging system, it automatically completes focusing, image capture, and analysis. The system detects various defects such as scratches, pits, chipping, and dirt on the fiber core end face, and evaluates the polishing quality of the end face. It is suitable for incoming inspection before optical device assembly and finished product re-inspection after coupling, ensuring the transmission performance of the optical coupling link.
