Darmstadts Fluoreszenzmikroskopie Ausbildungs Center @ Technische Universität Darmstadt

The D’FACTU core education center is aimed to provide the basics for teaching fundamental principles and modern applications in fluorescence microscopy. The education center is open for all departments and was initiated by the departments of Chemistry (FB 7), Material and Earth Sciences (FB11) and Biology (FB10).


The Darmstadt Fluoreszenzmikroskopie Ausbildungszentrum an der Technischen Universität (D'FACTU) provides modern fluorescence microscopes for teaching. Twelve identically configured Zeiss AxioVert A1 microscopes are available, which are also equipped with digital cameras and laptops. Image acquisition is made possible via the Zeiss Zen software.

In addition, there are smaller numbers of configurations available for reflected-light fluorescence microscopy, as well as objectives with high magnification. The microscopes are available for courses, including interdisciplinary courses. Bookings can be made via the tuinfra portal. The microscopes can be found there under the provider “FB10 Biology Teaching”.
