Example of a Kretschmann configuration for the analysis of SPR and LMR. In this case, the polarized light coming from the transmitting mirror TX is coupled through a prism to a coated glass slide so that the light beam is reflected in the interface at the desired angle θ1. The coated side is facing a sample tray containing the media whose refractive index is being measured. The reflected beam is collected by the receiving mirror RX.
