NOTE
A more detailed discussion of the worm tool is provided in Chapter 4: Probes Chapter 4: Probes.
When the scan-limit is enabled, the limit boundary can be configured to prevent scanning within a speci-
fied number of pixels from the edge of the field of view. Limiting worm tool scanning to the center of the
field of view eliminates the effects of lens-edge aberrations.
Enter the desired boundary distance into
the Max distance from edge... field.
Specifying pattern file names
Whenever the pattern tool is taught a new pattern, it can be saved automatically in the Parts folder using a
default filename, or can be saved in another folder using a user-specified filename.
The default file naming convention is:
Part name_Pattern (n).5pt
Where n is incremented for each new file.
Check the Prompt for pattern file name... box to specify a
pattern file name and storage location whenever a pattern
is taught to the pattern tool.
FOV spherical and NLEC corrections
Normally, measurements are made at or near the center of the optical system to avoid aberrations normally
present near lens edges. Spherical and NLEC corrections compensate for
these aberrations, but can only be enabled by OEMs and distributors after
performing specific calibration procedures.
NOTE
Contact your OEM or distributor for more information regarding these two correc-
tions.
CAUTION
Do not change the status of the Enable FOV spherical correction or Enable FOV
NLEC check boxes without specific instructions from your OEM or distributor.
