Pannoramic 250 1.15 User’s Guide 4 Software Description
Focus
To define focus limits, select Limiting the range checkbox. 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
.
Note:
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.
Manual Focus
By selecting the Use manual focus box, you can preset the coarse focus value. By activating
the Coarse focus function, the lower limit value is set to -200, and the upper limit value is
set to +200 of the current focus value.
Note:
Before entering coarse focus value, turn live image on and select a
suitable exposure time.
You can accept the current z-value by clicking Set Value. This is recommended for a very flat
specimen.
