Figure 9-3. Measurement setup when flatness mirrors are not used
If you will use a flatness mirror for one or more lines, leave at least a
102 mm (4 inch) border along one edge. This border allows sufficient room
for you to place the flatness mirrors.
The other sides require only a 51 to 76 mm (2 to 3 inch) border. Figure 9-4
shows an example of the measurement grid necessary when flatness
mirrors are used.
