WebIntroduction to Waveplates. The interaction of light with the atoms or molecules of a material is wavelength dependent. A result of this dependence is the resonant interactions related to material dispersion. Birefringence is another consequence of such resonant interaction, which is the change in refractive index with the polarization of light. WebAn advanced class of retardation plates enables the operator to introduce variable amounts of phase shift in order to offset specimen birefringence. These devices, as discussed above, are termed compensators and are …
