Principle of focal correction by the PM method. (a) Notations for planes and axes used in the text. (b) The wavefront disturbed by the aberration of the FE lens results in the focal broadening at IP (top). The correction of the wavefront by the PM results in the diffraction limited focal spot at IP (bottom). (c) 1: The single point generated at OP by the measured TM, 2: output point image generated at IP by the TM, and 3: output point image generated at IP after applying the PM. (d) Line profiles for 1 (black), 2 (green), and 3 (red) in. (c) OP: object plane. FE: fish-eye lens. PM: phase mask. TL: tube lens. IP: image plane. Scale bar: 20 μm.
