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