Chapter 2 Linear Measurements
Mounting and Aligning the Optics on the Target Machine
2-10 Measurements Reference Guide
4 Determine how to position the optics. See Figure 2-5 for sample setups,
and use the following guidelines:
• Mount one optic where the tool mounts. Mount the other optic where
the work piece mounts. Make sure the interferometer assembly is
between the retroreflector and the laser head.
• If you want to measure along an axis perpendicular to the laser beam
as it leaves the laser head, mount the interferometer assembly on a
part of the machine that does not move.
