Chapter 9 Flatness Measurements
Completing the Set Up Flatness Screen
Measuring the remaining lines on the grid
To measure the remaining lines on the grid, follow these steps:
1
If you have not already done so, select Next Line on the Analyze Data:
FLATNESS screen.
The Set Up FLATNESS screen (Figure 9-12) is displayed.
You can change the measurement units and optics' direction of travel on
the Set Up FLATNESS screen using the instructions in "Completing the
Set Up Flatness Screen," earlier in this chapter.
2
If you are not using flatness mirrors, move the laser head so it points
along the next measurement line.
If you are using flatness mirrors, continue with step 3.
3
Set up the optics for the measurement.
If you are not using flatness mirrors, set up the optics using the
appropriate instructions in "Mounting the optics," and "Aligning the optics
if you are not using flatness mirrors" or" "Aligning the optics if you are
using flatness mirrors" earlier in this chapter.
If you are using flatness mirrors, set up the optics using one of the setups
shown in Figures 9-15 through 9-17.
4
Align the optics using the instructions in "Aligning the Optics," earlier in
this chapter.
5
Align the laser beam to the optics' travel path using the instructions in
"Aligning the Laser Beam to the Optics' Travel Path," earlier in this
chapter.
6
Check the alignment for beam strength using the instructions in
"Checking the alignment for beam strength," earlier in this chapter.
7
Repeat the steps in "Measuring the first line on the grid."
