Weboptical measurements carried out below the glass transition temperature, the intrinsic birefringence was found to de crease with increasing k. For the sample k =0.7, the … WebBirefringence in an optical element leads to different optical path lengths, hence different wavefront aberrations, depending on the incident polarization state. Considering a single ray, the difference in the OPD of the two eigenpolarizations is referred to as the retardance, which is usually given the symbol δ.
