The KeyLab Optical Spectroscopy in all its aspects offers versatile possibilities for characterizing the electronic and structural properties of condensed matter. At the BPI, the focus of interest is on synthetic polymers, biopolymers, organic, molecular materials and supramolecular structures. The focus of the KeyLab is to provide measuring stations and methods that go far beyond the capabilities of standard absorption and emission spectrometers, thus making them accessible to a wider range of users without the need for in-depth expert knowledge.
