For us, W3+ Jena is an inspiring meeting place that brings together innovative companies, research institutions, experts and students. The event brings the diverse network of the technology region to life.
Over the years, the W3+ Fair has established itself in the Central Hesse region as an indispensable source of inspiration for local industry with a far-reaching ripple effect. We are proud to be the initiator and thus part of this success story. The underlying cross-industry concept drives the companies and thus the region forward.
Just as a prism unfolds the colors of light, the W3+Fair in Jena unveils the latest developments and technologies in precision and optics. The W3 in Jena is a real highlight for me! It's not just a trade fair, but also a tribute to the innovative strength and expertise that makes Jena so special as a globally recognized center of optics. Young talents and experienced experts come together here, even beyond the borders of Central Germany, to exchange knowledge and shape the future together. The spirit of research and passion for precision that drove Ernst Abbe and Carl Zeiss back then is alive and well here.
The W3+ Fair is an excellent platform for networking research and industry even more stringently and thus generating new innovations in photonics. The W3+ Fair is a great asset for Jena's “Optics Valley”.
Since 2020, the en-tech.talks have provided information on trends and developments. In different thematic blocks, companies present their product concepts, strategies, research results and thought-provoking ideas in numerous keynotes.
