INNOVATION SHOWCASES You can explore our full selection of innovation showcases on our website.

Raman imaging microscopy: the analytical multi-tool Join the audience for a live webinar on 22 April 2021 sponsored by WITec exploring the principles of 3D Raman imaging. Raman spectroscopic imaging is a powerful, versatile and increasingly common microscopy technique that can quickly identify molecules in a sample and visualize their distribution in three dimensions. This fast, non-destructive and label-free chemical characterization method offers enormous potential to physicists in many fields of research.
