Back in Berlin, Herrmann Haensch founded a workshop at Adalbertstrasse 82 and later at Karlsstrasse 8 and manufactured microscopes.

On April 24, 1864, Herrmann Haensch and the mechanic Franz Schmidt founded the company Franz Schmidt & Haensch in Berlin, at Dragonerstrasse 19. Franz Schmidt was responsible for the saccharimeters and polarization instruments and Herrmann Haensch for microscopes and spectroscopes.

Herrmann Haensch constructed a trichina microscope in 1864 according to the specifications of Rudolf Virchow . The mechanical precision and quality of their work in particular led many scientists to the workshops of Franz Schmidt and Herrmann Haensch.

Herrmann Haensch was a co-founder of the Berlin Mechanics Association (today the German Society for Mechanics and Optics ) and a founding member of the Physikalisch-Technische Reichsanstalt (PTR / PTRA), today's Physikalisch-Technische Bundesanstalt .

The last microscopes were manufactured by Wilhelm Haensch in 1893.
