It is the aim of this unit to provide instruments covering the whole application spectrum of advanced light microscopy and to make them available to researchers from the CRG as well as for visitors from other research institutions.

As Core Facility for light microscopy, the unit provides a number of advanced light microscopy systems, equipment for sample preparation and maintenance prior to imaging and resources for the subsequent processing of the image data.

The staff assists researchers in the experimental planning of light microscopy experiments and provides the in-depth training for the operation of the microscopes and for specific imaging techniques. Additionally, support is provided in the processing, rendering and analysis of the acquired datasets. If needed, custom analysis routines will be designed.
