Abstract
In this work, we explore the use of Generated Jacobian Equations (GJEs) for the inverse design of freeform micro-optical surfaces. We demonstrate the integration of this design technique into an applied pipeline targeting 3D printed freeform micro-optics fabricated via two-photon polymerization (2PP). This work establishes a bridge between alternative design tools and cutting-edge micro-fabrication technologies, opening new opportunities in the field of engineered micro-optics. We demonstrate this via two representative examples, a round top-hat and a fringe pattern projection freeform lens.
Key words: Inverse design / Freeform micro-optics / Two-photon polymerization
