Pannoramic SCAN II 2.2.0 User's Guide
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.
5.2.2.3 Exposure Indicator
Exposure time for the live image can be calculated by using the Calculated Exposure time function
. It is available to switch between microsecond, millisecond, and second units for the reading of
exposure time.

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 define exposure time weight, and in the DG the amount of digital gain is
displayed. It is also available for you to enable Extended Focus (EF) and/or Z-stack (ZS) functions in
this field.
Exposure Settings
You can set the Exposure time weight (%) here (displayed under TW in the Channel Settings frame).
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.
To prevent over-exposure, the Excitation intensity (%) value can be
modified by the software when calculating Auto Exposure time.
