Measurement of refractive index of isotropic particles by incorporating a multifunction spectrophotometer and immersion liquid method.
We propose a sequence of transmission and reflection measurements that makes it possible to get a relatively accurate estimate for refractive index of optically isotropic powder materials. This method makes use of immersion liquids and a multifunction spectrophotometer, which we have constructed recently. As an example we present data for CaF(2).
