摘要

A He-Ne laser device has been used for refractometric measuring of a number of optical plastic (OP) specimens. We applied an ellipsometric laser system for the index of refraction initial determination. A table of the experimentally obtained refractive indices of various types of the principal and some new developmental OPs at the laser wavelength λ = 632.8 nm is illustrated. The dispersion coefficients often American, Japanese and German OP samples were computed using a modified Cauchy's dispersive equation. A table of OPs' refractive indices calculated at twenty laser wavelengths in the spectral area from 405 nm (GaN LD) to 1064 nm (YAG devices) is presented.
