Abstract:
1. A surface plasmon resonance fluorescence analysis device for measuring fluorescence emitted by excitation of a fluorescent material labeled on a specimen by an electric field based on surface plasmon resonance, the surface plasmon resonance fluorescence analysis device comprising: a chip holding portion which is configured to detachably hold an analysis chip including a prism having a metal film formed on a predetermined surface thereof; a light source portion which emits excitation light for causing surface plasmon resonance on the metal film; and an incident path adjusting portion which allows the excitation light to enter the prism of the analysis chip held on the chip holding portion by reflection of the excitation light emitted from the light source portion, wherein the incident path adjusting portion includes a reflective member having a reflective surface formed thereon for reflecting the excitation light from the light source portion, and a driving portion for driving the reflective member, and the driving portion is configured to change a position of the reflective member and to adjust an orientation of the reflective surface in such a manner that the excitation light entered the prism is reflected at a specific position on the metal film.
