A process monitoring system for an additive manufacturing apparatus includes a scanner, a sensor device, and an optical focus-tracking device. The scanner includes an optical adjustment device that directs a melting beam emitted by a laser melting device onto a construction plane to generate a melting section of the construction plane. The sensor device may detect reflected radiation from the melting section and generate sensor data indicative of a size, shape, and/or temperature corresponding to the melting section. The optical focus-tracking device includes a focusing lens located between the scanner and the sensor device. The focusing lens may be actuatable by electronic machine data derived from the sensor data to impart a first focus adjustment with respect to the reflected radiation detected by the sensor followed by a second focus adjustment with respect to the melting beam directed by the optical adjustment device.
