| contents | Three-dimensional (3D) nano-printing via two-photon polymerization offers unparalleled design flexibility and precision, thereby enabling rapid prototyping of advanced micro-optical elements and systems, including hybrid achromats, diffractive and flat optics, millimeter-sized lenses, fiber-optic sensor heads, and photonic waveguides. These elements have found important applications in endomicroscopy and biomedical imaging. The potential of this versatile tool for monolithic manufacturing of dynamic micro-opto-electro-mechanical systems (MOEMS), however, has not yet been sufficiently explored. This work introduces a 3D nano-printed lens actuator with a large optical aperture, optimized for remote focusing in miniaturized imaging systems. The device integrates ortho-planar linear motion springs, a self-aligned sintered micro-magnet, and a monolithic lens, actuated by dual micro-coils for uniaxial motion. The use of 3D nano-printing allows complete design freedom for the integrated optical lens, while the monolithic fabrication ensures inherent alignment of the lens with the mechanical elements. With a lens diameter of 1.4 mm and a compact footprint of 5.74 mm, it achieves high mechanical robustness at resonant frequencies exceeding 300 Hz while still providing large a displacement range of 200 um (+- 100 um). A comprehensive analysis of optical and mechanical performance, including the effects of coil temperature and polymer viscoelasticity, demonstrates its advantages over conventional MEMS actuators, showcasing its potential for next-generation imaging applications. |
