Meet decision-makers, developers, and innovation leaders—two days packed with technology, networking, and business at the Optikzentrum Mittelhessen.
Not only was the world-famous Leica camera invented here, but the W3+ Fair is also “Made in Wetzlar.” The Wetzlar Network industrial network launched the trade fair in 2014 in collaboration 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. Come to the W3+ Fair and talk to the global players in person!
Learn more, expand your network, and experience two days of trade fair action on
March 18 and 19, 2026, focusing on the future technologies of optics, photonics, electronics, and mechanics.
