3D Printing of Optics: The Manufacturing of Polymer Optics via Inkjet Printing Tuesday 13 October · 8:00 to 8:45 am Location: Highland A/B

Joris Biskop LUXeXceL Group BV (Netherlands)

Via a digital design (CAD-file) the op-tical design is converted into a print file. These drive the inkjet printhead inside of the manufacturing printer, this printhead ejects droplets of a

specially developed monomer mixture that is sensi-tive to UV light, in the specific coordinates defined by the converted design. These droplets are cured via UV light and form a solid layer, this process is repeated until an 3D printed optic emerges.  LUXeXceL has developed this technology that they can produce parts, accurately, transparent, smooth and at production speeds.  Also discussed: The design for manufacturing, the optical parameters, and the part quality.

Joris Biskop currently CTO of LUXeXceL Brought two generations of inkjet printers to market and led pioneer work in optimizing acrylic materials for use in inkjet technology. Author and inventor on 5 patents.

Laser Polishing of Glass Tuesday 13 October · 8:45 to 9:30 am Location: Highland A/B

Christian Weingarten Fraunhofer-Institut für Lasertechnik (Germany)

The manufacturing of nonspherical optics in small lot sizes is time con-suming and hence more expensive compared to the manufacturing of

spheres. But, since nonspherical optics exhibit several advantages the demand for aspheres is steadily in-creasing. With laser processing, a decoupling of work piece and tool geometry is achieved, which enables the manufacturing time being nearly independent from the optics geometry.  A laser based process chain for optics manufactur-ing, which is being developed at the Fraunhofer ILT Generally, each process step for optics manufac-turing can be conducted with laser radiation. How-ever, each process step can be used as self-standing process and hence implemented in a conventional process chain.  To manufacture an optic with laser radiation three laser based process steps are consisted in the process chain. In a first step the geometry is generated from a glass preform. Using a CO2-Laser material is ablated by evaporation.

 The second step of the Laser based process chain is the Laser Polishing for reducing the resulting roughness of the high speed laser ablation. For Laser Polishing, CO2 laser radiation is used due to the high absorption coefficient of glass at l = 10.6 µm of about 80%. The laser radiation is absorbed in a thin surface layer with a thickness in fused silica of σopt <10 µm. Hence, the thin layer of the glass surface can be heated up just below evaporation temperature. Due to the surface tension and the reduced viscosity the roughness can flow out.  To reduce the resulting waviness of the polishing step a third process step is necessary. First, the surface is measured and subsequently the shape deviation is reduced by a High Precision Laser Abla-tion step. For the form correction CO2—or ultra-short pulse laser radiation is used.  In the presentation results for all three steps with a focus on laser polishing will be shown.

Christian Weingarten studied material science at the RWTH Aachen University in Germany (2008 – 2013). Since November 2013 he has been doing his doctor-ate at the Fraunhofer Institute for Laser Technology in Aachen. His research interest in the field of laser material processing include the laser polishing as well as the development of a laser based process chain for manufacturing of optics.

Light-based technologies respond to the needs of humankind

Join us in celebrating the International Year of Light

The International Year of Light is a global initiative highlighting to the citizens

of the world the importance of light and light-based technologies in their lives,

for their futures, and for the development of society.

We hope that The International Year of Light will increase global awareness of

the central role of light in human activities and that the brightest young minds

continue to be attracted to careers in this field.
