PROBLEM TO BE SOLVED: To provide a detection system for a detection target region having excellent fluorescence detection sensitiveness.SOLUTION: A detection system for a detection target region includes at least an illumination means to irradiate illumination light and irradiate excitation light to a detection target region, a fluorescent material which emits fluorescence by receiving excited light, a first imaging means to image illumination light reflected by the detection target region, and a second imaging means to image the fluorescence emitted from the fluorescent material. The detection system for the detection target region is characterized by satisfying the relation of λ1Max<λ2MIN, where λ1Max is the upper limit of wavelength range λ1 of the illumination light and the exciting light irradiated by the illumination means, and λ2MIN is the lower limit of a wavelength range λ2 which the second imaging means can image.COPYRIGHT: (C)2013,JPO&INPIT【課題】蛍光の検出感度の優れた検出対象部位の検出システムを提供する。【解決手段】検出対象部位を照射する照明光及び励起光を照射する照明手段、励起光を受光することで蛍光を発する蛍光物質、検出対象部位で反射した照明光を撮像する第1の撮像手段、蛍光物質が発する蛍光を撮像する第2の撮像手段、を少なくとも含み、照明手段が照射する照明光及び励起光の波長領域λ1の上限をλ1Max、第2の撮像手段が撮像できる波長領域λ2の下限をλ2MIN、とした場合、λ1Max<λ2MINの関係を満たすことを特徴とする検出対象部位の検出システム。【選択図】図1
