For nearly half a century, there were two Carl Zeisses. One based in the Federal Republic of Germany, or West Germany. The other in the German Democratic Republic, or East Germany. 

The Carl Zeiss of today is the Western German variant. Their work in lithography and EUV sits on the cutting edge of what is possible in nanoscale technology.
