Focus on Microscopy 2021
Porto, Portugal
March 28 - 31, 2021

Dear Colleagues

After the unfortunately cancelled FOM2020 due to the Covid-19 Pandemic, we would like to announce FOM2021, the next conference in the FOM series. The conference is scheduled to take place from Sunday March 28 to Wednesday March 31, 2021. Please note that this will be in the week before Easter 2021.

At present it is not clear if/what Covid-19 Pandemic restrictions  are in effect in the period of the conference. Therefore, the precise details of the format of the FOM 2021 conference are not clear yet. However, we aim to hold the conference on location in Porto as planned. Please keep an eye on this website and your e-mail for updates.

The FOM2021 Porto  conference venue will be:

Centro de Congressos da Alfândega do Porto
Rua Nova da Alfândega
Edifício da Alfândega
4050-430 PORTO

As a record of the cancelled FOM2020 conference, find under "Program cancelled FOM 2020 (Osaka)" the original program of accepted contributions as announced before the conference cancellation on February 6, 2020.

We originally hoped to organize the FOM 2021 conference in Osaka-Japan, but the Osaka Convention Center venue was not available for this period. However, we do aim to organize the FOM 2022 conference in Japan, once more together with Katsumasa Fujita and Satoshi Kawata. We want to extend our gratitude for their tireless efforts for organizing the cancelled Osaka conference.

FOM2021 in Porto will be the continuation of a yearly conference series (since 1988) on the latest innovations and developments in mostly optical microscopy and their application in biology, medicine, and the material sciences.

If you wish to be kept informed on updates, please leave your email address at We hope to send a more detailed announcement with respect to the upcoming FOM2021 Porto conference in September this year.

Key subjects for the conference series are the theory and practice of 3D optical imaging, related 3D image processing, and reporting especially on developments in resolution and imaging modalities. The conference series covers also the rapidly advancing fluorescence labeling techniques for confocal and multi-photon 3D imaging of -live- biological specimens.

Typical topics of the upcoming FOM conference include:

• Theory and practice of confocal and multiphoton-excitation microscopy • Super-resolution, nanoscopy imaging: from PSF engineering (4pi, SIM, STED), fluorescent activation/quenching, stochastic/centroid (PALM, STORM, GSDIM, SOFI and related techniques) to TIRF • 3D and 4D live cell and tissue imaging • Adaptive optics for microscopy • Light sheet microscopy • Phase/interference based microscopies, • OCT, holographic, endoscopy • Advanced fluorescence imaging/spectroscopy: FRET, FRAP, FLIM, FCS, SOFI • New fluorescence probes, proteins, quantum dots, single molecule imaging • Clearing and expansion techniques. • Coherent non-linear microscopies: SHG, THG, SFG, CARS. • Multi-dimensional fluorescence and Raman spectroscopy imaging • Correlated microscopies, light/electron, etc. • Laser manipulation and tracking, photo-activation • Fast acquisition, automated and high-content microscopy • 3D image processing and visualization for multidimensional data

A technical exhibition will be an integral part of the upcoming FOM conference. Detailed information about the previous FOM conferences of the last 20 years can be found on this website under the “History” button. From 2004 onwards also with one page abstracts of the presented contributions. Please note also the "Search FOM database" button for full searches through the whole FOM archive over the years
