Live
To display a live image of the current specimen in the Live image display field, click
sample. This option has no effect on a running digitization process where no live image is
displayed.
To display a live image during scanning, select Show images during scanning in the Service
tab.
Focus
To define focus limits, select Limit focus range. Set the upper and lower limits by selecting
the desired value in the selection boxes. This is useful if Auto Focus does not find the focus
on the specimen, but on the coverslip. Also, this makes the focusing sequence faster.
By using Set Current, the Lower limit value is set to -32 of the current focus value and the
Upper limit value is set to +32 of the current focus value.
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 Automatic mode. The manual
focus is mainly for setup purposes, not for using the product as a traditional microscope.
Define the manual focus step size by adjusting the Step size slider.
Search for the sharpest focus on the current field of view automatically by clicking
If you want to speed up the process, turn off the live image display,
because this reduces the processing speed of any concurrently running
function.
Extended focus mode (optional)
This determines features of the resulting virtual slide.
By choosing this option, the software selects the sharpest image from each focus level for
each image field, and combines them into one single image. Therefore those parts that
were blurry in auto/manual focus will also be sharp. This method guarantees the maximum
depth of sharpness, however, it reduces digitization speed.
