Coarse alignment
Note: Refer to the information in section “Tips for steering the beam path” on page 26 for
tips on how to adjust the beam path. Disable the laser emission and insert the alignment
tool, with the beveled-end inserted half-way into the output port of the SuperK CONNECT.
Note: Insert the alignment tool gently. The tool can damage the optics if inserted entirely
and with force.
Procedure 4 Coarse alignment
In this procedure, the Alignment tool is inserted into the CONNECT output port. The tool
has a pinhole within it that the beam is aligned with during the procedure.
1. Insert the Alignment tool with the beveled-end inside the CONNECT. Figure 12
shows a cutaway view of the Alignment tool inserted.

2. Tighten the lock screw so that the alignment tool is firmly held in the output port. This
increases the accuracy of the alignment.
3. Enable emission from the SuperK laser.
4. The beam enters the alignment tool. In order to exit the alignment tool, the beam
must be centered with the pinhole sized pupil machined inside the tube, see
Figure 12 which shows the beam passing through the pinhole.
5. With a laser viewing card suitable for the beam color, adjust the beam path, using the
CONNECT thumbscrews, until a spot on the target is centralized within a minimized
halo and with the maximum brightness as shown in
Figure 13 . If the spot is offset
within its halo, the beam path is incorrect, and not centered in the pinhole.
Note: Refer to the following section “Tips for steering the beam path” on page 26 .
