Supplementary information
Lenses for picture processing applications have their optimum exposure perform
ance at a short distance from the object. The minimum object distance MOD is the
shortest distance (distance between the front line and the motive) which can be
focussed sharply with the focal ring.In order to reduce the MOD, you can use inter
mediate rings or extension tubes to increase the distance between the lens and the
CCD sensor.
The maximum object distance is reduced more than the minimum object distance,
so that with greater lens extension it is no longer possible to focus via the focal
ring of the lens.Focussing then takes place by adaption of the exposure distance.
Use the values for focussing and for the viewing range listed in the following
S
table as reference values for ascertaining the exposure distance.
If necessary, adjust the exposure distance by means of the dove−tail fastening
S
of the Checkbox.
Use the CheckKon or CheckOpti software for checking and optimizing the
S
settings.
