Finite voxel size compensation for microprinting of parabolic X-ray lenses by two-photon lithography

Abstract

3D-microprinting by two-photon lithography can be applied to fabricate X-ray lenses. However, when the lens’ curvature radius approaches voxel size, the lens’ refractive surface essentially differs from the defined model. This shape distortion leads to defocusing of X-ray irradiation and astigmatism. In current work we suggest the compensation of the parabolic lens model taking into account finite voxel size.
