Deutsches Optisches Museum (D.O.M.) currently is undertaking three major projects:
The latter enables to understand the development of optics and photonics and may be a starting point for novel concepts in optics & photonics. E.g.: (a) fluorescence microscopy started in 1902, (b) light-sheet microscopy was introduced in 1903, (c) microscope objectives with N.A. of 1.60 were made in 1889, (d) Mach-Zehnder interferometers enabled the characterization of models in wind-channels with field-of-view of up to 90 cm2 in 1944, and (e) resolution targets for microscopy with a pitch of 110 nm were produced in 1873.
