3D printed complex microoptics – Presented by Prof. Dr. Harald Giessen , University of Stuttgart ,at the 4D Printing & Meta Materials Conference, which takes place on 1 February 2017 at Brightlands Chemelot Campus in Sittard-Geleen, The Netherlands.
In this talk, I will introduce femtosecond 3D direct laser writing for the manufacturing of complex microoptics. We can manufacture singlets, doublets, and triplets with freeform aspheric surfaces and diameters of down to 100 µm. The surface roughness is below 20 nm, and the shape accuracy is below one wavelength. We achieve high-resolution imaging with reduced aberrations over very large fields of view up to 70°. We print our complex microscope objectives directly on single-mode as well as multicore fibers, directly onto CMOS image sensors, as well as onto LEDs and other substrates. Our system is well suited for novel endoscopy, compact and integrated imaging systems and sensors, as well as integrated illumination systems.

About 4D Printing & Meta Materials Conference
Making and utilizing new materials to improve our life is a defining feature of mankind. We moved on from the stone age, to the bronze age, to the age of silicon and plastic. Now we are at the edge of a new episode, where technological breakthroughs allow us to create, investigate and dream of a total new range of structured forms of matter.
Two fields emerge strongly:
- 4D Printing offers a streamlined path from idea to full functionality.
- Mechanical metamaterials are structured materials with mechanical properties defined by their structure rather than their composition.
These are highly promising disciplines which develop in a synergistic manner, and which aim at creating entirely new forms of matter, which will lead to applications that have not yet been conceived.
