  • Surface plasmon resonance light pipe sensor
    Patent number: 5991048
    Abstract: The present invention provides SPR sensors in which the sensing element is a planar lightpipe. The sensors of this invention include configurations which employ multiwavelength light incident on the SPR sensing area at a single angle or at a range of angles. Sensors of this invention also include configurations that employ monochromatic light at a range of angles. Many of the configurations of the SPR lightpipe sensors of this invention involve imaging of input light through the lightpipe. In one embodiment, the invention provides a first order SPR sensor system in which the sensing element is a planar lightpipe. Light coupled into the lightpipe reflects off an SPR sensing area positioned on an external surface planar surface of the lightpipe.
