Adaptive system able to switch between angular resolved SPR and SPR imaging

An optical setup able to switch between the surface-plasmon resonance (SPR) angular resolved spectroscopy in Kretschmann's configuration and SPR imaging is presented. The system's concept is based on an adaptive optical module which allows to perform the two complementary measurements by sharing all optical elements and avoiding any moving part. Among the main advantages given by this switching feature there are both the fast calibration capability of the SPR image by using the angular resolved spectroscopy and the optimization of the SPR chip probing area.
