A maker of optical and photographic equipment.

The company has its origins in Jena, an industrial city in Germany, in 1846. There, Carl Zeiss, a faculty member in Jena University, started up his company producing optical equipment.

They were a dominant force in photography and microscopy for much of the 20th century, and responsible for many advances in both fields. The history of Carl Zeiss is a long and tangled one, involving many take-overs and mergers (like many other companies), as well as restructuring due to World Wars (spinning off Pentacon in East German).

Today, they still make fine research microscopes and photographic lenses under the Zeiss name, and cameras under the Contax name.
