MTF GRAPHS The MTF is shown in each case for the maximum aperture 1.25 and the aperture values 2.0 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.

DISTORTION

VIGNETTING

Distortion is the deviation of the real image height (in the picture) from the ideal image height. The relative distortion is the percentage
deviation. The ideal image height results from the object height and the magnification. The image height of 21.6 mm is the radial distance
between the edge and the middle of the image field for the format 24 mm x 36 mm. The graph of the effective distortion illustrates the
appearance of straight horizontal and vertical lines in the picture.

Vignetting is a continous decrease of the illumination to the edges of the image field. The graph shows the percentage loss of illumination
over the image height. 100% means no vignetting.
