3D-Printed Microoptics by Femtosecond Direct Laser Writing

Femtosecond direct laser writing offers unique possibilities for the fabrication of microoptical components and systems. Almost unrestricted 3D design freedom, high resolution and accuracy, as well as alignment-free assembly enable direct printing of complex structures with optical functionality. Various imaging and illumination optics are presented and discussed (Most of the contents shown are a directly translated from the PhD thesis “Design, Simulation und Prozessoptimierung fur das 3D-Laserdirektschreiben von Mikrooptiken” by Simon Thiele, University of Stuttgart (2019)).
