Notes:
This study presents an enhanced common path interference system designed to measurethe refractive index of crystal optical components. The proposed system is based on the classicMichelson interferometer and comprises a frequency stabilized helium-neon (He-Ne) laser, a beamsplitter, a fixed mirror, an adjustable mirror, and a light detection system. The waveplate of interestwas clamped to a rotatory motor and positioned between the beam splitter and the fixed mirror. Therefractive index of the waveplate was then derived from the change in rotational angle of thewaveplate as it moved from one position of minimum interference to the next. The measurementsystem proposed in this study is simple in construction, straightforward in operation, and robust tothe effects of experimental noise. Furthermore, the system is a non-contact measurement system,and hence does not damage the optical component of interest. The experimental results are found tobe in good agreement with the theoretical results. Therefore, the proposed system provides a viablemeans for the rapid experimental evaluation of the optical characteristics of quartz components
