4.7.2 Pinhole adjustment
☞
In all existing standard configurations, the pinholes have already been adjusted at the factory.
These settings are taken over for active operation when a standard configuration is loaded.
If you want to create a setting that differs from the standard configurations, adjust the pinhole
as follows:
Manual pinhole adjustment
The position of the pinhole relative to the detector in terms of X-Y-Z coordinates contributes substantially
to image optimization.
Requirements to make pinhole position changes visible immediately:
The image must be scanned by the continuous scan method.
Select a fast scanning speed (see next section).
Measurement with Average Number 1 only (no averaging of several measurements).
On the Channel Settings panel (click on <Channels> button in the "Scan Control" window),
select the pinhole diameter so as to have the best possible image contrast (Airy Units 1.0).
Click on the <Maintain> button of the main menu toolbar.
This opens another, subordinate toolbar in the main menu.
