Task 3: Aligning the Optics
In this procedure, you make sure that the optics are aligned with the laser
beam path and with each other. Follow these steps:
1 Set the turret ring on the laser head to OTHER (Figure 4-7).
Figure 4-7. Front of the laser head
2 Rotate the laser head’s target into position over the lower port by turning
the lower aperture control.
3 Pass your finger between the interferometer assembly and retroreflector.
One of the alignment dots on the laser head should flicker. This is the
retroreflector return beam. The other is the interferometer assembly
return beam.
NOTE
You may need to adjust the height of the interferometer and or the
reflector to see both return beams on the target in the lower port on the
laser head.
