WebWhat does retardation of phase mean? Information and translations of retardation of phase in the most comprehensive dictionary definitions resource on the web. Login WebGenerally, optical elements for introducing a controlled amount of optical retardance are called retarders. Retardation effects also occur upon reflection at a dielectric interface with non-normal incidence; here, the retardance can be calculated with Fresnel equations.
