The Day of Light returns to Vienna in 2022!

One Day, three unforgettable events!

Event 1 - Experiments in the historic Tram

Friday, 13. Mai 2022

17:00 - 19:00 o'clock

Attention: new access point on the Schwedenplatz

On May 13, Photonics Austria invites to a special event on the occasion of the International Day of Light. Starting at 5:00 p.m., everyone will have the opportunity to get to know photonics and its numerous applications from different views at Schwedenplatz in Vienna and to experience a variety of experiments up close. According to the motto “Shaping the future”, you will find out what light can do, where it is already an integral part of our everyday life and which technologies we can look forward to in the coming years.


There is something for everyone, so don’t miss out! 

Event 2 - Photonics 4 Smart and Green Cities

Monday, 16. Mai 2022

10:00 - 14:00 o'clock

17 o’clock, MCI Innsbruck

On the occasion of the INTERNATIONAL DAY OF LIGHT on May 16, 2019, the PHOTONICS AUSTRIA platform organized an interesting series of lectures for more than 120 guests in the impressive ambience of the MCI University of Applied Sciences on Maximilianstraße in Innsbruck, featuring well-known Austrian photonics companies and experts in the field, in order to offer a broad audience insights into this exciting future technology.

In the run-up to the main event, school students from Innsbruck and the surrounding area were able to gain valuable experience of scientific work with the Fraunhofer Institute’s BaKaRos system.

Heinz Seyringer (V-Research), Stefan Bernet (Med.-Uni Innsbruck), Albert Fiedler (Swarovski Optics), Carina Buchholz (Zumtobel) and Gregor Weihs (Uni Innsbruck) gave insights into the following topics:

These topics were underlined with applications by Wilfried Pohl (Bartenbach), Elisabeth Kostal (FH Vorarlberg), Alexander Wörle (KDG) and Truong Le (Fraunhofer Institute).

The cozy setting in the beautiful ambience of the “Alte Post” provided for an interesting exchange among the guests afterwards.

Due to a technical problem with the camera and the audio, the presentations are unfortunately not available as video!
