Refractive index considerations of polymers for optics

Refractive data of different types of acrylic, styrenic and polycarbonate polymers for optics is presented in the visible and near-infrared spectrum. Results are compared to the information of analogues materials given in catalogues of optical design programs and technical data of plastic producers. Deviations are observed due to the production conditions and brand peculiarities. Dispersive properties are examined and comparative and test dispersion curves are illustrated applying the developed OptiColor program. Influence of environmental conditions on stability of polymer properties is discussed. Refractive and dispersive tolerances in optical design are considered.Refractive data of different types of acrylic, styrenic and polycarbonate polymers for optics is presented in the visible and near-infrared spectrum.
