In this report dispersion properties of different types of optical polymers are discussed on the base of measured
refractive indices and the Cauchy–Schott approximation. A number of dispersion curves are presented in the
visible and near infrared spectral regions between 400 and 1060 nm. A comparison with some optical glasses with
similar refraction is performed. The nonlinear dependence of dn=d¸ of polymer materials and test glasses on the
wavelength is calculated and analyzed. Normalized dispersion curves at 550 nm and 880 nm are presented to
illustrate better the dispersion of the polymers in the considered spectral regions, separately. Abbe numbers are
calculated to exhibit the mean and partial dispersion.
PACS numbers: 42.70.Jk, 78.20.Ci, 78.30.Jw

Paper indicates two things.
There is a flat dispersion for all plastics and most dispersion difference is at lower wavelenghts.


I WANT TO ASK , V879 CHART is indicates the partial dispersion. It changes from 52 abbe number at Optorez and 100 at Zeonex.
Do higher or lower partial dispersion number indicates higher effect. And lower wavelenghts indicates higher frequency and blue partial dispersion. Am I right ? Does it makes blue photographs. I need the opposite
