Fraunhofer IOF presented new systems at the LASER World of PHOTONICS 2019

Our Fair Highlights 2019

Additive manufacturing of lightweight mirrors and systems

 

Telescopes for space applications are based on precise, mass-reduced and stable arrangements of several mirrors. Additive manufacturing processes offer new concepts for the production of metal optics that can overcome the specific limitations of conventional manufacturing technologies. Fraunhofer IOF presents a lightweight mirror system manufactured in such way, whose internal and external housing structures have been produced by selective laser melting (SLM) of aluminium-silicon material. The mass reduction of a single mirror component reaches up to 64 %, using an internal structure which is not manufacturable by conventional techniques.

Optical quantum technologies

 

The Fraunhofer IOF is a pioneer in applied research on photonic quantum technologies. For the first time, developments in the field of quantum imaging will be presented at this year's LASER World of PHOTONICS. It is a quantum photonically based imaging system. By using high-power sources of entangled photons, such as those developed at the Fraunhofer IOF, future imaging systems based on quantum technologies can become even more compact, e.g. for applications in biology and medical technology.

Fast adaptive focusing mirrors for materials processing

 

The fast adaptation of the laser focus in materials processing requires adaptive optics with fast response times. In order to enable the user to easily integrate and upgrade existing systems, Fraunhofer IOF presents a focusing mirror that is designed as a 90° deflecting mirror and achieves a reaction time of a few milliseconds. On display will be a version for laser cutting and laser welding, as well as a further version with integrated plane field correction for applications in laser structuring systems. The technology was developed within the BMBF project »Piezo-driven beam shaping for highly dynamic laser materials processing in 3D space«, which is part of the smart³ innovation network.

Ultra-compact multispectral camera

 

The ultra-compact multispectral camera system developed at the Fraunhofer IOF records twelve individual spectral and spatially resolved channels simultaneously. The innovative concept is based on the integration of a microoptical multi-aperture objective and a customized monolithic filter-array, which comprises 4x3 expanded filter tiles. The required new filter concept was realized by a combination of gray-scale lithography and dry etching processes for the lateral structuring of the filter design and thus the individualization of the parallelized imaging channels. Possible applications are e.g. precision farming, security and surveillance, biomedical engineering, recycling or industrial sorting.
