  • Patent number: 12196674
    Abstract: The present invention relates to providing a detection device that uses surface plasmon resonance to detect the presence or the amount of a substance to be detected, in which a detection unit can accurately detect scattered light without detecting stray light, and can accurately determine an irradiation angle of excitation light. This detection method uses the detection device that uses surface plasmon resonance to detect the presence or the amount of a substance to be detected. A detection range control unit controls a detection range of a detection unit so that a detection range utilized when the detection unit detects scattered light emitted from a metallic film and front a region on the metallic film differs from a detection range utilized when the detection unit detects fluorescence emitted front a fluorescent substance labeling the substance to be detected winch has been captured by a capturing body.
