Abstract

The dispersion of birefringence of three polymers commonly used in photoelasticity studies has been measured at several ir and visible wavelengths and the results have been correlated with transmittance spectra. The change of stress-optic coefficient in the visible region ranges from 6% for CR-39 and 16% for P-6 to 17% for polycarbonate. The dispersion of birefringence is anomalous on the short-wavelength side of an absorption band, and normal on the long-wavelength edge. The dispersion is small in spectral regions that are far from resonance frequencies.
