Abstract
A surface plasmon resonance fluorescence analysis device emits a light beam to a prism in which a metal film is formed on a prescribed surface while changing an angle of incidence relative to the metal film in a state in which the light beam is totally reflected, measures light generated on a surface of the metal film, determines an angle at which the light beam enters the metal film based on a change in intensity of the measured light, adjusts the emitting direction of the light beam so that the light beam enters the metal film at the determined angle of incidence, and measures fluorescence generated on the surface of the metal film in a state in which the light beam is emitted the adjusted direction.
