SURFACE PLASMON RESONANCE DEVICE FOR FIELD MEASUREMENT

摘要

The present invention relates to a surface plasmon resonance apparatus for field measurement comprising: a main body case in the form of a pen having an accommodating space inside and a combination opening whose one edge area is opened; a sensor module having a metal thin film on one side and a coupler in the other side, and combined in the combination opening of the main body case to allow the metal thin film to be exposed to the outside of the main body case, and the coupler to face the inside of the accommodating space; a light source part installed in the accommodating space to irradiate measurement light in the form of parallel light in the longitudinal direction of the main body case toward the sensor module; a cylindrical lens including a first cylindrical curved part to allow the measurement light to move toward the sensor module by converting the measurement light to the form of wedge light, and a second cylindrical curved part wherein reflection light in the form of wedge light reflected by the sensor module enters, and then the reflection light is converted into the form of parallel light and emits, and arranged between the light source part and the sensor module to allow a light path of the measurement light and a light path of the reflection light to be symmetrical in the longitudinal direction of the main body case; and a light receiving part arranged in the light path of the reflection light emitted from the second cylindrical curved part to receive the reflection light. The present invention has an effect of easily measuring a field by removing a fluid control system such as a pump inducing flow of a fluid or the like when being applied to a biotechnology or environmental measurement.
