Noémie and Edlyn took part in the “Principles of Light Microscopy” course from April 1-5. Over the course of one week, a tight-knit group of 12 scientists (including PhD students, postdocs, and a BioImage analyst) discussed the basics of microscopy, optics principles, setup and techniques behind the different types of microscopes, digital imaging, and ended with extended resolution in fluorescence microscopy. The program contained a nice mix of theory learning, hands on experience, demos, and short presentations by other imaging specialists in our institute. This microscopy course is held annually and is organized by our institute’s Light Microscopy Facility (LMF). This year, the course was held in a new venue, in our neighbouring Center for Systems Biology Dresden (CSBD). Great location, making the course seem like a 1-week microscopy retreat!
