ABSTRACT:
Systems and methods for improved correction of intrinsic birefringence are provided. Two pairs of optical elements correct for intrinsic birefringence of optical materials. A combination of design criteria for the set of optical elements, including refractive power type, intrinsic birefringence signs, and crystal axis rotation, is used to correct for intrinsic birefringence.
