| Abstract: | A new type of a spherical-wave source for precise interferometry based on a fiber probe for a nearfield microscope is proposed. Data on distortions of generated wavefronts are reported. For the optical numerical aperture NA = 0.24, the root-mean-square distortions do not exceed λ/2000. |
