ABSTRACT:
The present invention provides SPR sensors in which the sensing element is a planar lightpipe. The sensors of this invention include configurations that employ multi-wavelength light (including broad band and white light) incident on the SPR sensing area at a single angle or at a range of angles. Sensors and probes of this invention also include configurations that employ monochromatic light at a range of angles. Many of the configurations of the SPR lightpipes of this invention involve imaging of input light through the folded lightpipe. In one general embodiment, the invention provides a SPR sensor system in which the sensing element is a folded planar lightpipe.
