Mounting and Aligning Optics for X-Axis or
Y-Axis Measurements
This section explains how to assemble, mount, and align optics for
straightness measurements along the X-axis or Y-axis.
Mounting the optics
To assemble the optics and mount them on the machine, follow these
steps:
1 Connect the interferometer to its base using the attachment screws
provided (Figure 5-6).
2 Connect the post to the interferometer using either of the following
methods (one method uses the height adjuster, the other does not):
• Remove the large knurled knob from the height adjuster, connect the
height adjuster to the interferometer’s base plate using the
attachment screws, and screw the post into the height adjuster
(Figure 5–6). Use this method if you plan to make other types of
measurements later; it will take less time to change the optics.
• Screw the post directly into the interferometer’s base plate
(Figure 5-7).
3 Secure the post in the machine spindle.
