Modification of Low Refractive Index Polycarbonate for High Refractive Index Applications [PDF]
Polycarbonates and polythiourethanes are the most popular materials in use today, for optical applications. Polycarbonates are of two types which fall in the category of low refractive index and medium refractive index.

Refractive index and temperature coefficient of refractive index of Al2O3- and SiO2-water nanofluids
Measurements are made of the refractive index and temperature coefficient of refractive index (∂n/∂T) for two nanofluids, Al2O3-water and SiO2-water, over the temperature range 20–40°C at a wavelength of 632.8 nm.

Refractive index of rubber [PDF]
Abstract This paper presents an exploratory study of the refractive index of rubber. Previous observations on the refractive index of rubber have been, for the most part, restricted to transparent samples. In the present investigation, however, by using reflected light rather than light at grazing incidence, it was found possible to extend the ...
