A 3D printing apparatus for manufacturing a workpiece has a first radiation source to carry out a non-linear absorption polymerization and a second radiation source to carry out optical coherence tomography. A first beam path is traversed by the first radiation and a second beam path is traversed by the second radiation. The first and second beam paths are formed completely independently of one another.

An optical system with an entrance pupil, has a first aperture diameter, an exit pupil and a reflective or transmissive filter element spaced at a distance from the entrance pupil, which is designed and arranged such that a second diameter is illuminated on the filter element by a beam passing through the entrance pupil and spreading divergently from this. The second diameter corresponds to n times the first aperture diameter, and n is a number greater than 1, as a result of which the local angular spectrum at each point on the filter element is n times smaller in comparison to the entrance pupil. The filter element selectively reflects or transmits to the exit pupil at each point only a predetermined spectral range. An optical imaging unit comprising the filter element is provided, which images the entrance pupil onto the exit pupil.
