1. A process monitoring system for an apparatus for additively manufacturing three-dimensional objects, the process monitoring system comprising:
a scanner comprising an optical adjustment device configured to direct a melting beam emitted by a laser melting device onto a construction plane to generate a melting section of the construction plane;
a sensor device configured to detect reflected radiation from the melting section and to generate sensor data indicative of a size, shape, and/or temperature corresponding to the melting section; and
an optical focus-tracking device comprising a focusing lens located between the scanner and the sensor device, the focusing lens actuatable by electronic machine data derived at least in part 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.
