Paper Abstract

Two Fresnel birhomb (lambda) /4 retarders have been realized from glass and fused quartz respectively, both having identical geometrical parameters but different residual stress birefringence of the raw material. Their behavior as achromatic retarders were examined in a null spectroscopic ellipsometer. The way in which the performances of this type of retarder depend on the residual stress birefringence is presented.
