Popis: Two nondestructive methods of X-ray lens testing—X-ray microtomography and phase contrast introscopy—are analyzed and compared. Refractive lenses fabricated via laser stereolithography are used as a comparative object. The first samples of photopolymer lenses have been created via the rotation method, in which a capillary filled with a Dikhrom Lyuks liquid photopolymer is exposed to UV radiation during centrifuge rotation. Lens samples have been fabricated at the centrifuge’s angular velocities lying in the range from 3000 to 5000 rpm. The features of photopolymer transition from the liquid state into the solid phase under UV irradiation have been investigated to estimate their influence on the formation of the required shape of a refractive profile.
