With almost 100 years of company history, the Zanger brand is a guarantee of quality and reliability for measuring microscopes. Founded in 1920 in the center of German optics in Wetzlar and now, in 2018, moved to the Franconian Lake District. With a new name and new ideas, TROSA GmbH continues to offer the well-known range of products from Zanger for research, teaching and industry. The combination of existing products, a modular system for individual microscope solutions, the development and simulation through optical design and the customer-specific software solution offer a perfect service for our customers. We only sell to traders / resellers.
The company Karl Zanger and Sons has been operating under the name TROSA GmbH since October 1st, 2018. TROSA GmbH thus enters into the delivery obligation of Karl Zanger and Sons.
