Lens Correction
1.
The signal screen is displayed at the end of the installation procedure as a
chance to optimize the straight-through signal before the measurement
is taken. This may be necessary in some system configurations involving
the ND filter wheel (see Section 2.2 System Components). When
finished, or if no optimization is required, cancel to escape the signal
screen.
2.
The software will acquire data in the straight-through position and fit for
the Delta Offsets introduced by the focusing lenses. These offsets will be
written to the Configuration as mentioned earlier.

3.
After the focusing probes are installed, the AOI will move to a safe
position (i.e., 70°) and the

panel will
update as shown below.

4.
If configured, the software will then automatically correct the Angle
Offset and the Receiver Alignment Camera Offset.
Note:
With the focusing probes attached, the base cannot be operated in
the straight-through position. The limit switches behind the probes
prevent the stage from moving past 75° (or 65° in some
configurations). This prevents the probes from running into the
sample stage and damaging them.
