Title:
SURFACE PLASMON RESONANCE DEVICE FOR ON-SITE MEASUREMENT
Document Type and Number:
WIPO Patent Application WO/2015/178587
Kind Code:
A1
Abstract:
The present invention relates to a surface plasmon resonance device for on-site measurement, comprising: a pen-shaped body case having formed therein an accommodation space and a coupling aperture having an opened edge region at one side thereof; a sensor module having a metal thin film disposed on one side thereof and a coupler disposed at the other side thereof, the metal thin film being exposed to the outside of the body case and the coupler being coupled to the coupling aperture side of the body case such that the coupler faces the inside of the accommodation space; a light source unit for irradiating measurement light in the form of parallel light toward the sensor module along the longitudinal direction of the body case, the light source unit being formed within the accommodation space; a cylindrical lens comprising a first cylindrical curved surface part which converts the measurement light to the form of wedge light and directs the wedge light toward the sensor module, and a second cylindrical curved surface part on which the reflected light in the form of wedge light from the sensor module is incident and emitted after being converted to the form of parallel light, the cylindrical lens being arranged between the light source unit and the sensor module such that the light path of the measurement light and the light path of the reflected light are symmetrical to each other with respect to the longitudinal direction of the body case; and a light receiving unit for receiving the reflected light, the light receiving unit being arranged on the light path of the reflected light emitted from the second cylindrical curved surface part.
