Not only was the world-famous Leica camera invented here – the W3+ Fair is also “Made in Wetzlar.” The Wetzlar Network industry network launched the fair in 2014 together with Fleet Events – and found the ideal location in its Hessian hometown. The leading center of the optics industry is home to more global market leaders than almost anywhere else. The W3+ Fair is a convenient place to meet these global players face-to-face!
Learn, expand your network, and experience two days of exhibitions on March 18 and 19, 2026, focusing on the future technologies of optics, photonics, electronics, and mechanics.
