Booming high-tech region in Hesse

It’s not only the world-famous Leica camera that was invented here – the W3+ Fair is also “Made in Wetzlar”. The industrial network Wetzlar Network launched the trade fair in 2014 in conjunction with FLEET Events – and found the ideal location in its home city in the state of Hesse. Around the leading centre of the optics industry there are more world market leaders than almost anywhere else. At the W3+ Fair, you can easily talk to the global players face-to-face! Learn new things, expand your network and enjoy two trade fair days, on 13 and 14 March 2024, devoted to future technologies in the fields of optics, photonics, electronics and mechanics.
