ZEISS microscopes visualize tiny structures in nano-dimensions, and highly efficient metrology systems guarantee productivity and quality assurance in industry. Prominent scientists put their trust in ZEISS microscopes when conducting their research. Robert Koch, who discovered the bacterium that causes tuberculosis in 1900, was just one of our famous customers. To this very day, researchers from all over the world use light, electron/ion and X-ray microscopes from ZEISS to make even the smallest structures and fastest processes visible.
