High-quality marking results are only possible if the working distance between the laser system and the component is optimally adjusted. With the new Auto Focus plug-in, the laser beam is automatically focused on the object to be marked. Changing components made of different materials, with different part heights or widely varying production tolerances are marked precisely and with high repeat accuracy using the auto focus function. Automatic focusing guarantees precise, high-contrast marking results, especially for focus-critical applications such as annealing or black marking. The new Auto Focus plug-in is available for fiber lasers in the Economy and Business Fiber series in the standard design and therefore complements the performance spectrum of Magic Mark V3.
