  • Patent number: 7545500
    Abstract: The present invention discloses surface plasmon resonance phenomenon measuring equipment comprising: (1) a prism, (2) a sensor wherein a plurality of measuring cells are formed in m rows and n columns on the bottom face of the prism, (3) a light source for radiating a laser beam, (4) a first optical system wherein m optical units each having a rectangular parallelepiped shape and having a translucent film formed along the diagonal surface of the rectangular parallelepiped are arranged continuously, (5) a second optical system wherein mn optical units are arranged continuously and a reflected lights group is radiated toward the measuring cells, (6) a photodiode array detectors group of m rows and n columns, arranged on the extensions of reflected lights group, and (7) a polarizer interposed between the first optical system and the prism, and/or between the prism and the photodiode array detectors.

  • Publication number: 20070109541
    Abstract: Light (41) is emitted from a light source having a specific wavelength so as to form a line focus on a sensor including a prism (42) and a glass substrate (44). A sample cell and a reference cell are disposed such that their sensing portions lie on the line focus at a predetermined distance, and surface plasmon resonances are generated at the sensing portions to reduce the intensity of the light reflected from the sensing portions. The beams of the reflected light are reflected from light-splitting mirrors (53) having different angles with the beams maintaining a distance equal to the predetermined distance between the sensing portions, and thus the reflected light is split into two optical paths. An electrode-type combination sensor cell (47) having sensing films corresponding to the sample portion and the reference portion is pressed on an adhesive optical interface film (43) disposed on the prism (42), having a refractive index matched with that of the prism (42).
