Rough Alignment of the Laser Beams

Rough alignment may be required to keep the laser beam on the target as

the ﬁxtures are rotated. Either of these methods can be used:

• Visible Beam rough alignment – utilizes the visible laser beams

without the use of the analyzer

• Partial Sweep rough alignment – utilizes the partial sweep capabili-

ties of the analyzer

Visible Beam Rough Alignment

This adjustment must be performed in each of the movement planes (typi-

cally horizontal and vertical, when required). A horizontal adjustment is

shown in the following ﬁgure; duplicate the actions for vertical adjustments.

Rough Horizontal Laser Beam Adjustments
