MTF DIAGRAMS
Infinity (∞) Close distance (1 m)
MTF GRAPHS The MTF is shown in each case f or the maximum aperture and the aperture values 5.6 and 8.0 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 structur es
(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.
