For manual focusing define the manual focus step size by adjusting the
Step size
slider and use the
two arrow buttons to focus manually. This is useful when you are interested in an area that remained
blurry with
Auto Focus
(for example, the specimen is thicker in that area). This does not influence the
way slides are digitized in Auto focus mode.

Select the types of filters you want to use during scanning. You can select the filter types and the
number of channels to be used. The values in the
EXC
column define the excitation of the Lumencor
illumination, in
TW

DG
the amount of digital gain is
displayed. It is also available for you to enable Extended Focus (
EF

ZS
) functions in
this field.
Exposure Settings
You can set the
Exposure time weight (%)
here (displayed under
TW

Set Lumencor excitation intensity at the
Excitation intensity
(%)
field. The defined value will be used
as maximum when applying Auto Exposition time if you activate the
Max. excit. intensity
option.
Caution!
To prevent over-exposure, the
Excitation intensity
(%)
value can be
modified by the software when calculating
Auto Exposure
time.
