Zeiss is a German optics and optoelectronics group founded in Jena in 1846 that is owned by a foundation rather than by shareholders, which frees it to invest on very long horizons. Its most strategically important business supplies the optical systems inside extreme ultraviolet lithography machines, without which leading-edge semiconductor manufacturing would not be possible, and it also makes surgical and diagnostic ophthalmic equipment, spectacle lenses, industrial measurement systems, microscopes and camera optics. Headquartered in Oberkochen with a large site in Jena, the group employs tens of thousands of people and spends an unusually high share of revenue on research.
