The interface between the coverslip and the Rhodamine B solution was imaged with several objective lenses with different NA in the axial direction.
Both the fitted ESF and the derived LSF are shown in each condition including (a) NA0.3 objective lens (MPLFLN 10×, Olympus), R2 value, the goodness of fit, was 0.997 (b) NA0.7 objective lens (LCPlanFLN 50×, Olympus), R2 value was 0.989 (c) NA0.8 objective lens (MPlanFLN 50×, Olympus), R2 value was 0.915 (d) NA0.8w objective lens (LUMPLFLN 40×, Olympus), R2 value was 0.963 and (e) NA0.9w objective lens (LUMPLFLN 60×, Olympus) R2 value was 0.942.
