Optical methods such as ellipsometry, interferometry, spectroscopy, and surface plasmon resonance (SPR) have recently been used in developing optical sensors. SPR sensors have attracted attention due to their accuracy and sensitivity. Surface plasmons are waves created by the oscillation of free electrons that can be excited by light, between a metal and a dielectric medium. Sensors rely on the refractive index of the second medium to determine the resonance location. In this study, we used white light and total internal reflection through a cylindrical prism to focus on an SPR optical setup and Sensors with 50 nm coverage and 632 nm reference laser wavelength. This experiment evaluates the intensity and reflection index of surface plasmon resonance at different wavelengths to determine the electrical property ɛ of the surrounding medium and its application in assessing different materials.
