3D printed complex microoptics: A new paradigm in optics manufacturing (Conference Presentation)
Author(s): Harald Giessen

Paper Abstract

We demonstrate a fundamental paradigm shift in microoptics manufacturing. Using femtosecond two-photon 3D printing with 100 nm spatial resolution, the time from lens design and structural assembly layout to manufacturing and optical testing can be reduced to less than 24 hours. Even complex microscope objectives with multiple aspherical and non rotationally symmetric freeform surfaces can be manufactured. We demonstrate diffraction limited performance and MTF measurements across a large field of view of such systems that can be as small as only 100 µm in diameter, directly fabricated onto the ends of optical fiber tips. Other applications such as phase shapers or miniaturized illumination systems are also presented.
