Effektive Verzeichnung
MTF GRAPHS The MTF is shown in each case for the maximum aperture and the aperture value 4.0 and 5.6 for long focusing distances (infinity).
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.
