| Summary: | Evanescent wave is the result of attenuated Total Reflection (ATR), Surface Plasmon Resonance (SPR) occurs at a specific angle on condition attenuated Total Reflection (ATR). When a beam is passed through a prism, the beam will be reflection on the part of the prism which is in contact with the sample. The result of this reflection to be captured by the detector. On the condition of Surface Plasmon Resonance (SPR), weaken the intensity of the reflected beam of laser light that occurs because refracted exponentially away from the boundary of the medium. Labview-based program has been created that can be used as a tool for experimental Surface Plasmon Resonance (SPR), using Motor SHOT 602 and Lock In Amplifier (SR510). Programs that have been made already equipped with the condition automatic of movement Motor 2 (Prisma), Motor 1 (Detectors), Readings Voltage detectors by Lock In Amplifier (SR510) and storage of results (time, a position of the motor 1 and 2, the voltage read Lock in Amplifier). Automation program is made by studying the way of the light at Surface Plasmon Resonance (SPR), to determine the relationship between the rotation angle prism and the angle of rotation of the detector to the incident angle of light, it can be used for control the position of the sample on the prism and the detector in a program based on labview. |
