● Highlights

Micro-optical elements: freeform optics, lenses, gratings, prisms and micro-lens arrays, processed via Two-Photon-Polymerization as complex optical structure or as master for replication technologies, based on UV curable and highly transparent inorganic-organic hybrid polymers.

Macroscopic elements: By means of 3D-Printing, optical macroscopic elements for illumination optics using highly transparent 3D printable hybrid polymers; The optical elements can be combined with printed baffle structures, mirrors, or scattering layers but also with conductive lines or integrated light sources, such as LED.

High-Temperature optics: Using printable polymer-based material and subsequent annealing steps, complex optical structures can be manufactured that provide a high thermal stability of > 400 °C. But even without thermal annealing steps, the materials can cope with thermal load of 200 °C and higher.
