Claim 14:
15. A method for operating the apparatus of claim 1 for additively manufacturing three-dimensional objects by means of successive layerwise selective irradiation and consolidation of layers of a build material which can be consolidated by means of an energy source, the method comprising:generating an energy beam with an irradiation device; partially reflecting the energy beam with at least one beam guiding element; transmitting a first beam part split from the energy beam from the at least one beam guiding element to a build plane; transmitting a second beam part split from the energy beam through or scattered at the at least one beam guiding element, from the at least one beam guiding element to a determination device; and determining, with the determination device, at least one parameter of the energy beam based on the second beam part, wherein the at least one parameter comprises at least one of: a focal position of the energy beam; or a focal shift of the energy beam.
