The concept of a tunable surface-plasmon resonance system able to switch between imaging and Kretschmann angular resolved systems by exploiting a tunable optical module is presented. This scheme allows to perform complementary measurements (SPR angular resolve and SPR imaging) on the same setup with no moving parts. Furthermore, this switching capability can be used to calibrate the imaging with the angular resolved measurements, to enhance the quality of the image and SPR curve and to change/optimize the penetration depth of the evanescent wave probe at the interface metal/target.

Abstract
The concept of a tunable surface-plasmon resonance system able to switch between imaging and Kretschmann angular resolved systems by exploiting a tunable optical module is presented. This scheme allows to perform complementary measurements (SPR angular resolve and SPR imaging) on the same setup with no moving parts. Furthermore, this switching capability can be used to calibrate the imaging with the angular resolved measurements, to enhance the quality of the image and SPR curve and to change/optimize the penetration depth of the evanescent wave probe at the interface metal/target.File in questo prodotto:
