Abstract:
A surface plasmon resonance imaging apparatus provides an improved optical assembly allowing fixed source and detector operating with a horizontal test surface for a more compact design. In a preferred embodiment, a mechanical linkage of planar mirrors provides a single point adjustment of angle of incidence and angle of refraction while maintaining a constant optical axis of the source and detector.
