The origin of the FOM conference series were the three-dimensional imagingcapabilities of confocal microscopes together with the associated 3D imageprocessing methodologies that developed in the mid 80's. The technology foroptical microscopy has been evolved rapidly with the development of optoelectronic technologies such as femtosecond lasers and highly sensitivephoto-detectors, together with a wide variety of new fluorescent stainingmethodologies and digital image analysis routines for 3D and live cell 4Ddata sets. Nonlinear optical microscopy including multi-photon excitedfluorescence microscopy, time-resolved micro-spectroscopy, and second-harmonicand coherent anti-Stokes Raman are making imaging of molecular compositionspossible. High-resolution optical microscopy, including near-field scanningoptical microscopy, four-pi confocal microscopy, and coherence probemicroscopy also constitute a major research topic that progresses opticalmicroscopy towards nanoscopy.

These timely conferences reflect and promote the most recent developments andoffer a most efficient meeting point for developers and users working in theserapidly evolving fields and play an important role in the dissemination ofinformation about new developments with special attention to joint applicationswith bioinformatics, nanobiotechnology and bioengineering. A technicalexhibition will show the most recent developments in microscopy andassociated techniques.

The present Focus on Microscopy 2011 conference in Konstanz, Germanyincorporates and can be seen as a continuation of the
