Accurate null polarimetry for measuring the refractive index of transparent materials

Not Accessible

Your library or personal account may give you access

Abstract

Simple null polarimetry is introduced to measure the refractive index n of transparent and semitransparent materials. For a linearly polarized incident light, the reflected polarization can be used to determine n with the Fresnel equations. This method is fast, convenient, and versatile enough to provide accurate results on small laboratory samples. Possible errors in experiments are analyzed, and ways to eliminate these errors are given. With our instrument, the uncertainty in the deduced n is ±0.0004. The accuracy is still within 0.1% for materials with high n and with the extinction coefficient of the order of 0.001. The method is also sufficiently accurate for characterizing the homogeneity of transparent materials.
