Zusammenfassung:To provide a portable SPR apparatus.SOLUTION: An SPR detection apparatus includes an optical system including a sensor member including a planar metallic layer, the sensor member being removably mountable to a housing. A first optical element directs an incident beam toward a rear side of the metallic layer at a predetermined range of angles to a normal to the sensor layer. A second optical element guides at least one reflected beam, corresponding to the incident beam, from the metallic layer to a transducer. The transducer converts incoming electromagnetic radiation to an electrical signal for transmission to a signal processor disposed in the housing and operatively connected to at least one opto-electrical transducer so as to detect a surface plasmon resonance angle. The first optical element is configured so that the at least one incident beam spans over at least 20°.SELECTED DRAWING: Figure 13 【課題】ポータブルSPR装置を提供する。【解決手段】SPR検出装置は、平面金属層を含むセンサー部材を含む光学システムを含み、センサー部材が、筐体に取り外し可能に搭載可能である。第1の光学素子が、センサー層に対する法線に対する所定の角度範囲で金属層の裏側に向けて入射ビームを方向付けする。第2の光学素子が、入射ビームに対応した少なくとも1つの反射されたビームを金属層から変換器に案内する。変換器が、表面プラズモン共鳴角を検出するために、筐体内に配置されて少なくとも1つの光電変換器に動作可能に接続された信号プロセッサへの送信のために入来電磁放射を電気信号に変換する。第1の光学素子が、少なくとも1つの入射ビームが少なくとも20°にわたって広がるように構成される。【選択図】図13
