To mark World Interferometry Day, we will be hosting an international scientific symposium at the Technical University of Ilmenau on April 20, 2026.

This year's World Interferometry Day will take place on April 15, 2026, to commemorate the groundbreaking development of the interferometer. Albert Abraham Michelson's ingenious invention over 140 years ago has become synonymous with high-precision measurement technology. Like no other technology, it embodies the art of measuring extraordinarily small quantities and effects. Pushing technology to its limits and challenging it to ever new heights of performance—that is the credo of modern laser interferometer technology.
