MTF DIAGRAMS
The MTF is specified for full stop and for apertures 2.8 and 5.6 for long
image distances (infinity). The contrast in percent is applied for 5, 10, 20,
40 Lp/mm above the height of the 35mm film for tangential (dotted line)
and saggital structures (continuous line) with white light. The 5 and 10 Lp/
mm give an impression of the contrast behavior for rougher object
structures, while 20 and 40 Lp/mm document the resolution capabilities for
fine and ultra-fine object structures.
