    • The plasmon resonance sensor (1) comprises a chip (2) of transparent plastic with a gold layer (3) made up of narrow part surfaces (4), arranged in a row, on the inner side of which light from a planar light source (12) is convergently guided. A Fourier lens (24) integrated in the chip (2) forms the reflected angular spectrum on the detector (23), arranged at a focal separation (F) from the integrated Fourier lens (24) for temporal determination of the incident angle with a resonant intensity minimum of reflected light. An incident lens (13) brings about imaging of the planar light source (12) in the form of lines of light on the part surfaces (4), which are further imaged in the form of lines of light on the detector (23).

    • The invention relates to a surface plasmon resonance sensor for the simultaneous measurement of a plurality of samples present in fluid form. The aim of the invention is to provide such a sensor which can be arranged into a defined array and where the surface plasmon resonance sensors can be produced using technology which is simpler and more economical than those produced according to the prior art. To this end several strip-like optical wave guides (2) are arranged on a planar support (1) at a defined distance to each other in such a way that their front faces (21, 22) are flush with opposite sides (11, 12) of the planar support (1). Each strip-like optical wave guide (2) in a section which is to be brought into contact with the fluid samples has at least one thin metal layer (3) which permits the excitation of surface plasmons. Means (14) are provided for which separate the measurement zones of the individual thin metal layers (3) from each other in such a way that each of the optical wave guides (2) can be assigned to only one sample.
    • 本发明涉及用于同时测量以流体形式存在的多个样品的表面等离子体共振传感器。 本发明的目的是提供一种这样的传感器,其可以被布置成限定的阵列,并且其中可以使用比根据现有技术制造的那些更简单和更经济的技术来生产表面等离子体共振传感器。 为此,几个带状光波导(2)以相互限定的距离布置在平面支撑件(1)上,使得它们的前表面(21,22)与相对侧(11, 12)。 要与流体样品接触的部分中的每个带状光波导(2)具有允许表面等离子体激发的至少一个薄金属层(3)。 提供了将各个薄金属层(3)的测量区域彼此分开的装置(14),使得每个光波导(2)只能分配给一个样品。
