Günter Schmahl (physicist)

from Wikipedia, the free encyclopedia

Günter Schmahl (born March 26, 1936 in Wilhelmshaven ; † August 14, 2018 in Göttingen ) was a German physicist , professor at the University of Göttingen and a pioneer of X-ray microscopy .

The focus and the essential importance of Schmahl's work lay in the development of full - field X-ray microscopy with soft X-rays . He was one of the first to recognize the potential of this method and the pioneering technological approach of using zone plates as lenses in such a microscope. Schmahl and his team continued to develop the chosen approach until it was ready for use in two- and three-dimensional imaging of biological samples.

Schmahl founded the Institute for X-ray Physics at the University of Göttingen and headed it until his retirement in 2002. He was one of the founders and the first organizing organizer of the International Conference on X-ray Microscopy, which has been held every three years since 1983 and biennial since 2008.
