Fraunhofer Institute for Silicate Research ISC
Booth number: C-32-8
For optical and opto-electronic applications, Fraunhofer ISC develops and licenses superior optical polymers and corresponding process techniques. Thereby, µm-structures, such as micro-optical components, wave guides, (freeform-) lenses and gratings but also illumination optics can be created. Additive process techniques are used in order to generate optical sub-µm resolution structures but also macroscopic elements of several cm with a high optical quality. The special materials developed at Fraunhofer ISC are thermally stable hybrid polymers (ORMOCER®) and composites as well as wet-processed inorganic layers. By this set of materials, a wide range of refractive indices and transmission properties can be addressed, also in combination with various electrical, mechanical, thermal or biological specifications. The objective of the R&D service of Fraunhofer ISC is the increasing of quality at lower cost using sustainable technologies.
Products & ServicesComplex Micro-optical elements based on inorganic-organic hybrid polymers
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.
