Hauser, Kugler, PI Physik Instrumente, Son-x, Trioptics and WZW Optic.

For the first time, the organisers of the W3+ Fair/ Convention 2020 are offering a high-tech congress in the form of the N-Tec Talks, where participants can find out about current trends, the latest technical developments and the legal framework on the core topics of the event parallel to the exhibition.

The W3+ Fair/Convention was initiated by local companies and the Wetzlar Network industry association and took place for the first time in 2014. Since then, the event has established itself as a networking platform for technology-driven innovations for visitors from the optics region Wetzlar/ Central Hesse as well as for national and international experts.
