title: Conoscopic evaluation of the birefringence of gradient-index lenses: infidelity sources.
abstract: Gradient-index lenses are samples whose special characteristics must be taken into account to design the optical polariscopes that can be applied in the evaluation of their birefringence. We discuss the main infidelity sources that modify the conoscopic patterns when a traditional polariscopic setup is used.
