  • Method of printing and implementing refractive X-ray optical components
    Patent number: 11919264
    Abstract: A method of fabricating a refractive optical element on a substrate may provide less expensive and more compact optics for an X-ray system. The method includes coating the substrate with a resin and providing radiation to a portion of the resin to cause two photon polymerization of the resin. The method further includes forming, by two photon polymerization, a first surface of a polymer refractive optical element from the resin. The first surface is disposed along an optical axis of the refractive optical element and the first surface has a roughness of less than 100 nanometers. Further, the method includes forming, by two photon polymerization, a second surface of the polymer refractive optical element. The second surface is disposed along the optical axis of the refractive optical element and the second surface has a roughness of less than 100 nanometers.
