•
Spot Size Step
(0.1 / 0.01 / 0.001)
This enables to set the accuracy of the spot size setting.
•
Enhanced Contrast slider besides Contrast
(Yes / No)
enables to show the Enhanced contrast control next to the
Contrast in the Detector module. In this case the corresponding
control in the Detector Settings module disappears.
•
Display Scanning Preset toolbar
(No / Yes)
Enables to show 6 preset scanning parameters at the toolbar.
Image and graphics
•
Restart Average Filter when magnification changes
(Yes / No)
•
Restart Average Filter when scan rotation changes
(Yes / No)
•
Restart Average Filter when beam shift changes
(Yes / No)
•
Restart Average Filter when stage moves
(Yes / No)
The above items enable to choose whether the image averaging
should be restarted when the indicated parameter changes.
Restarting the Average Filter causes the image to blink and get
noisier; on the other hand, the averaging slows down the image
response to the changed parameter.
•
Display beam icon in databar
(Yes / No)
Adds an active beam icon to the first data bar position.
•
Blinking pause icon during image integration
(Yes / No)
If Yes is selected, the blinking Pause symbol is displayed in quads
which are being stopped. Otherwise, the Pause symbol appears
only after the image acquisition has actually stopped.
•
Display Recording Movie message
(No / 1 second / 2 seconds / 5 seconds / 30 seconds)
At the beginning of the movie recording, this message could be
displayed in the recorded quads for a selected time period.
•
Hide Rotation controls when not used
(No / 10 seconds / 30 seconds / 60 seconds)
Specifies if and when the on-image Scan / Compucentric Rotation
control should be automatically switched off.
•
Display Scan Rotation in CCD quads
(Yes / No)
•
Display Tilt Corrections in CCD quads
(Yes / No)
The above two items specify if the Scan Rotation / Dynamic Focus
and Tilt Correction indicator and value should be permanently
displayed in the CCD image(s); only non-zero values are
displayed.
•
Reset Enhanced Image parameters on file open
(Yes / No)
When opening an image, applied enhancement corrections
(remembered for the quad) are reset irreversibly.
•
Post Proccessing
(
Standard
/ None / Custom...)
Sets the default Post Processing setting.
Microscope operation
•
Lower stage when venting the chamber
(Yes / No)
Specifies if the stage should automatically go to a low Z values when
venting the chamber. This is a recommended (not default) setting,
because it greatly diminishes the chance of hitting the pole piece
when closing the chamber doors after mounting a higher specimen.
•
Change magnification when pumping
(No / Set to 25× / Set to 100× / Set to 200×)
Specifies if the magnification should be automatically set to a low
value when the chamber is being pumped (presumably after
replacing the specimen).
