Sensor device for surface plasmon resonance.

摘要

Sensor device for surface plasmon resonance, comprising a transparent member (1), a layer (2) of metallic material applied to a substantially flat surface (10) of said transparent element (1), a light emitter (3 ) emitting light towards the transparent element (1), passing through said light said transparent element (1) and reflecting layer (2) of metallic material and photodetector means (4) adapted to receive light reflected from the layer ( 2) of metallic material. The light emitter (3) emits a divergent beam (5) and is arranged at a certain distance from the transparent element (1), which corresponds to the focal length of the lens, and said transparent element (1) it comprises a lens.
