MTF-graphs
The MTF is indicated at full aperture, at f/2,8 and f/5,6
at long taking distances (innity). Shown is the contrast
in percentage for 5, 10, 20 and 40 lp/mm accross the
height of the 35 mm lm format, for tangential (dotted
line) and sagittal (solid line) structures, in white light.
The 5 and 10 lp/mm will give an indication regarding
the contrast ratio for large object structures. The 20
and 40 lp/mm records the resolution of ner and nest
object structures.
