Abstract

Two-photon polymerisation (TPP) is an additive manufacturing tool based on laser direct writing with sub-wavelength resolution. It has received enormous attention in recent years because it enables the production of precision polymer micro-optics without post-processing steps as well as three-dimensional diffractive optical structures. However, TPP is still a laboratory-level technology which requires elaborate and time-consuming alignment steps. This paper will present our approach to automatize many of these steps.
