Abstract
An optical measuring device having a base for placing the measuring device and a targeting unit that is rotatable with respect to the base and defines a target axis for targeting a target object that is to be measured. The targeting unit has a first beam path for emitting optical measurement radiation in the direction of the target object that is to be measured. The targeting unit furthermore has a diffractive optical element (DOE), which is arranged or arrangeable in the beam path such that the optical measurement radiation is homogenized.

1-15. (canceled)
An optical measuring device for coordinative measurement of a target object, the optical measuring device comprising:
- at least one light source for generating at least one optical measurement beam;
- and
- a targeting unit that is rotatable relative to a base of the measuring device about at least one axis wherein the targeting unit defines a target axis for targeting the target object that is to be measured, and has a beam path for emitting the optical measurement beam in the direction of the target object that is to be measured,
- wherein the targeting unit has at least one diffractive optical element, wherein the at least one diffractive optical element is embodied such and arranged or arrangeable in the beam path such that the measurement beam is homogenized before emission.
A method for coordinative measurement of a target object with an optical measuring device, with targeting of the target object with a target axis of a targeting unit, wherein targeting is effected with emission of optical measurement radiation along a first beam path in the direction of the target object.
