I am looking forward to the upcoming W3+ in Jena because it provides an ideal platform for our local company to present itself on an equal footing with many other regional, national, and international exhibitors. I love the short distances, the high density of exhibitors, the high-caliber lecture program, and the enjoyable evening event. The sharp increase in the number of exhibitors shows that there is a great need in the region to showcase oneself, network better, and jointly initiate new projects in Central Germany—in an uncomplicated manner and across professional boundaries. The W3+ Fair absolutely lives up to this claim.
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”.
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.
Now in its third year and expanded to include a third (!) exhibition hall, the W3+ trade fair in Jena demonstrates the appeal of Thuringia as a business location. With exhibitors who are all key players in the photonics and precision supply industry, manufacturers, suppliers, and service providers from a wide range of growth industries can find inspiration and ideas for new and expanded partnerships in technical discussions. And besides, the region in and around Jena offers a multitude of other very good reasons (not only) to visit, in addition to its technological attractions!
