Ernst Abbe

Formulated by Ernst Abbe in 1873, the Abbe sine condition is a mathematical condition that must be fulfilled by a lens to produce sharp images without the optical aberration known as coma. This critical discovery established the theoretical foundation for modern precision lens design and high-resolution microscopy.

Ernst Abbe joined the Carl Zeiss optical workshop in Jena, Germany, in 1866 as a research director, eventually becoming a partner and later the sole owner. When Carl Zeiss died in 1888, Abbe established the Carl Zeiss Foundation, transferring his shares to the university and workers to fund ongoing scientific research.

Yes, working closely with glass chemist Otto Schott, Ernst Abbe developed the first apochromatic microscope objective lenses in the 1880s. These lenses successfully corrected for both spherical and chromatic aberrations at three different wavelengths, revolutionizing the capabilities of optical microscopes.

The Carl Zeiss Foundation, established by Ernst Abbe in 1889, is the sole owner of both Carl Zeiss AG and the Schott AG glass manufacturer. Abbe uniquely structured the foundation to guarantee the financial security of its workers and to fund scientific research at the University of Jena.
