MTF GRAPHS The MTF is shown in each case for the maximum aperture and the aperture values 5.6 and 8.0 for the close distance setting. The
contrast is plotted for 5, 10, 20, 40 lines/mm for the height of the format for tangential (dashed line) and sagittal structures (continuous
line) for white light. The plots for 5 and 10 lines/mm provide an impression of the contrast performance for coarser object structures
and the 20 and 40 lines/mm plots document the resolving power for fine and finest object structures.
