PROTOTYPES

Developing prototypes for addressed markets on basis of the technology platforms

On base of prototyping, performance of new technologies will be demonstrated.

Prototype I: Multi-channel optical sensor - Market " Information "

Partner: FSU Jena in cooperation with IPHT and FhG-IOF, TU Ilmenau

Based on the technology platform 3DFL, a multi-channel optical micro sensor was developed, which combines micro mechanical components (support structure SiO2), micro-optical (lenses and CGH) and nano optical elements (polarisers, phase plates, meta materials) to a new approach of integration concept, increased compactness and new functionality. A key element of this prototype are off-axis aspheric lens arrays, made by 3DFL. We challenged the integrating of nano optics, together with micro structured optics into a complex micro optical system and thereby reached more than just a linear lining up or scaling.

Prototype II: Adaptive optical system - Market " Production "

Partner: FSU Jena in cooperation with FhG-IOF, TU Ilmenau

The increasing use of high-energy laser sources with highest radiation quality in numerous applications of the material processing requires the use of adaptive optical systems that guarantee the radiation quality with high thermal load and variable environmental conditions, regularly. In particular, this is increasingly problematic in the beam shaping of laser sources for material processing, since deformations of the wavefront of the laser also can affect the treatment result. Furthermore miniaturization as well as simple and robust construction is demanded for mainly non-astronomical applications such as, confocal microscopes, digital cameras and high power lasers. The results can be summarized as follows: The first natural frequency of the mirror is larger than the required 1 kHz. The piezoelectric strain is stable over a wide temperature range. The mechanical finishing membrane allows heights up to 400 µm. The regulatory approach allows a control frequency of 559 Hz.

Prototype III: Micro optical bioreactor - Market " Life Sciences "

Partner: TU Ilmenau, FSU Jena, CiS GmbH

Task was to demonstrate the multi-functional collection of relevant physiochemical parameters for "Life Science" unsing a test object. This brought together mainly optical methods with microfluidic systems using micro-and nanoscopic methods to an integrative approach. The central unit in the circulation system is the micro bioreactor. The structure of the overall system of the optical micro bioreactor is a closed loop with different analysis modules (analysis of metabolites, AlGaN sensor system, temperature and flow measurement) and possibilities of manipulation (e.g. optical tweezers). Measurements can be accomplished both in the constant flow and in the segmented flow. Biochemical assay concepts in a miniaturized form could be integrated into the optical micro bioreactor could used manifoldly - among other things to the determination of relevant parameters in cell culture experiments.

Prototype IV: Optical particle sensor - Market " Environment "

Partner: CiS GmbH, FSU Jena

Development objective of the demonstrator is a light-scattering particle sensor for oil with particle sizes between 4 and 20 μm. A measurement range up to 20,000 particles/mL is sufficient for this sensor system. The basic concept uses the noise of scattered light as a measurement signal. The technological feasibility could be ensured by implementing the beam shaping element with help from the MORES ® technology platform.

Prototype V: Optical micro tracker - Market " Production "

Partner: TU Ilmenau, FSU Jena in cooperation with FhG - IOF

Position sensing in robots in most cases are calculated from angular sensor and/or length sensors along the arms of a robot or a manufacturing machine and therefore a reduced accuracy of the absolute position caused by adding of results has to be taken into account. Using the tool centre point (TCP) data can be sensed from fixed points by triangulation. In this way a miniaturized scanning system with integrated interferometers has been developed which has a very compact footprint. The demonstrator comprises a miniaturized optical tracker system as well as a required intelligent user system.
