Fraunhofer IOF presented new systems at the LASER World of PHOTONICS 2019
Additive manufacturing, quantum technologies, active optics for space applications – once again, the Fraunhofer IOF presented the latest cutting-edge technologies in optics and photonics research at the LASER World of PHOTONICS 2019 in Munich.
From June 24 - 27, 2019, experts were available at the Fraunhofer joint booth (Hall B3, booth 335) to answer questions and showcase »Photonics – Made in Jena«.
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.
Additively manufactured lightweight mirror made of AlSi alloy after final polishing step.
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.
Quantum Optical Imaging System – A robust monocrystal setup enables the examination of an object in the ultraviolet (UV) or infrared (IR) spectral range.
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.
Very high spatial resolution and real-time detection of 12 spectral channels in a very compact design - This is made possible by the ultra-compact multispectral camera of the Fraunhofer IOF.
