Claim 0:
1. An apparatus for additively manufacturing three-dimensional objects, the apparatus comprising:
an energy beam comprising:
a first beam part split from the energy beam reflected by an at least one beam guiding element, the first beam part extending from the at least one beam guiding element to a build plane; and
a second beam part split from the energy beam transmitted through or scattered by the at least one beam guiding element, the second beam part extending from the at least one beam guiding element to a determination device;

an irradiation device comprising the at least one beam guiding element, the at least one beam guiding element configured to partially reflect the energy beam; and
the determination device adapted to determine, based on the second beam part, at least one energy beam parameter, wherein the at least one energy beam parameter comprises at least one of:
a focal position of the energy beam; or
a focal shift of the energy beam.
