Newsletter 4/2019

Newsletter of the Fraunhofer IST

Editorial

Dear Readers,

“Plasma processes are at home here” - the motif of our Newsletter shows a model of the Fraunhofer IST in plasma, which plays an important role in our institute. Along with this impression, we would like to send you a warm Christmas greeting.

For the last time for this year, we are pleased to provide you with information concerning selected topics which have characterized our research work.

At the end of this special anniversary year for the Fraunhofer-Gesellschaft, there is a “quantum leap” in our “Answered…” section. But please be careful! Prof. Dr. Günter Bräuer explains what this actually means in physics. Read for yourself...

Furthermore, we would like to draw your attention once again to the opportunities for meeting the Fraunhofer IST scientists at trade fairs and conferences during the coming weeks. We are particularly looking forward to the International Conference on Coatings on Glass and Plastics ICCG13, which is being organized by the Fraunhofer IST for the fourth time. From 23rd to 26th March 2020, international experts are being invited to Braunschweig in order to discuss the latest trends and developments in the field of glass and plastic coatings. In the accompanying technical exhibition, companies will have the opportunity to present themselves and their products.

We hope you enjoy reading our Newsletter and wish you a relaxing holiday and a good start to the New Year. We look forward to continuing to provide you with exciting news from the Fraunhofer IST.

Highlights

At the end of the year, we would like to present two highlights from the Fraunhofer IST's project work:

 

Safe water for rural areas in Southern Africa

The Fraunhofer IST is working together with European partners to provide more than 100 million people with access to clean water.

 

Fraunhofer lighthouse project develops materials for sustainable tandem solar cells

Solar cells with the highest level of efficiency provide electricity cost-effectively, consume less space and fewer resources and enable the creation of new products which can be charged via solar cells. In the Fraunhofer lighthouse project “MaNiTU”, sustainable tandem solar cells on the basis of new absorber materials are being developed.

Research

Optical interference filter systems and their production form a central focus of the Fraunhofer IST. You can look forward to two exciting articles on new research results from our area of precision optics: the development of a narrow-band infrared bandpass filter with broad blocking for the optimization of LIDAR systems and the simulation of optical precision films on curved components:

 

Narrow IR bandpass filter on 3D surfaces

With the development of a process for the direct deposition of a bandpass filter on the lens, the Fraunhofer IST is providing a building block for more compact and lighter LIDAR systems.

 

 

Simulation of optical precision coatings on curved components

A digital twin, based on data from a previous multi-scale process simulation performed at the Fraunhofer IST, enables the iterative optimization of shaper masks in order to solve this coating problem.

Dear Professor Bräuer, what is actually a ”quantum lap”?

Trade fairs and exhibitions

In the coming months the Fraunhofer IST will participate at the following trade shows, conventions, and events:

ak-adp Workshop

Braunschweig, March 25 – 26, 2020

”Innovative combination processes with precise spatially resolved plasma functionalization at atmospheric pressure” are the topic of the Fraunhofer IST at the Workshop.

Hannover Messe 2020

Hannover, April 20 – 24, 2020

Along a model process chain for the production of cutting tools the Fraunhofer IST demonstrates its expertise in surface engineering and the associated product and production systems.

Conferences

As a scientific partner, the Fraunhofer IST is involved in the following conferences:

 

Int. Conf. on Coatings on Glass and Plastics

Braunschweig, March 23 – 26, 2020

The conference program and exhibitor list are now online.

 

Future Production of Hybrid Structures FPHS

Wolfsburg, May 27 – 28, 2020

The Call for Abstracts runs until January 10, 2020. 

Lectures

During the next quarter, many Fraunhofer IST scientists will be travelling internationally to conferences, conventions, and seminars in order to present their research results to expert audiences. We give you an overview of the planned talks below:

Plano-convex lense coated with a bandpass filter (at 670 nm). The coating has a special gradient, which ensures a constant spectral position of the central wavelength on the lense regardless of the position. The light in the remaining spectral range (340–1100 nm) is heavily blocked. Total coating thickness 22 micrometer, number of coatings.
