Successful application of optical materials in lens design is based on the knowledge of their refractive and dispersive properties in the considered spectral region. We have obtained precise refractometric data of various optical polymers in the visible and near-infrared area. Different refractive index measuring techniques have been used. On base of the detailed study of refractive, dispersive, thermal and other important material characteristics of polymers, optical design of all-plastic systems for laser applications is proposed: a laser expander for 532 nm emission wavelength and a focusing microlens intended for reading/recording laser heads of DVD discs at 650 nm. Geometric and wave aberrations are computed and minimised.
