3.1.2.2 Taper Error
Taper error results when the prism base module (discussed in section 2.4, item 6.4.4) does
not reflect the laser light exactly 90° (i.e. non-perpendicularity between the rotating line
and the rotating axis). The end result is a laser rotating surface that is not a plane, but a
tapered one as shown in the figure to the right. The value A in the left target shares the
same symbol as the one in the right target during the check, that is, A
optical wedge of the laser output window to make the rotating laser beam and rotating axis plumb beam. The details are listed as
follows:
a.
Remove the top cover as discussed in section 1 of this document
b.
Screw the wedge out of its base with special spanner as shown in the
figure to the right.
c.
Adjust the laser to the zero position of the target.
d.
Loc-tight adjust after it has been set.
Note: Only one direction (X or Y) is necessary for the adjustment.
