Polymer index of refraction
WebThe refractive index is the ratio of the velocity of an electromagnetic wave in vacuum relative to its velocity in the material of interest. Refractive index can be measured between 1.30 and 1.71 at a wavelength of 589.3 nm, using an Abbe refractometer. WebAll-polymer multilayer hollow core photonic fiber preforms were fabricated using consecutive deposition from a solvent phase of two polymers with high and low refractive indices (RI).
