  • Fluorescence imaging device
    Patent number: 9046489
    Abstract: An excitation light from a first light source is adapted to be irradiated to a subject without passing through an objective lens so that the first light source and the subject may be arranged to be adjacent to each other. As a result, an excitation light having a high intensity of radiation may be irradiated to the subject to obtain a strong fluorescence signal. In addition, since the optical path of the excitation light from the first light source and the optical path of the fluorescent emission light emitted from the first dichroic mirror and the white light do not coincide with each other, a high S/N ratio may be obtained.
