It started with diatoms

Pattern laying of diatoms is science as well as art. The thin layers of the tiny silicate structures glitter in polarized light. Both laying of the structures and examining the diatoms require microscopes. Johann Diedrich Möller was fascinated by diatoms and, after founding his optical company in 1864, produced the microscopes as well as the diatom samples for university students over several decades.

Today the target is the same:
recognition of complex biological structures
