Dispersion properties of polystyrene, silica and water from wavelengths of 400–800 nm. Dispersion properties of polystyrene, silica and water were calculated using the Sellmeier equations for published materials [53–55]. Median refractive index (geometric mean in case of Gardiner et al) measurements for different EV sources were acquired from the literature [22,23,34,40,41].
