3. If boresight is required, refer to Figure 2-34 Cross-Hair Pattern to understand how the adjustment screws
on the lens mount affect the corresponding cross-hairs on the test pattern.
NOTE:
The capscrew, ( Figure 2-
35 ) may be under a plastic cap, remove and retain before adjusting.
4. Use a 5mm Allen™ key to loosen the 3 locking setscrews on the lens mount, see Figure 2-35 Screw
Locations , below.
NOTE:
The setscrews must be backed out several turns, so that they do not contact the
inner lens mount plate.
5. Fine tune the focus of cross-hair pattern I by adjusting the appropriate capscrew, see Figure 2-35 Screw
Locations . Adjust until the cross-hair image is in focus with minimal flare.
6. Adjust cross-hair pattern II, by adjusting the appropriate capscrew, see Figure 2-35 Screw Locations.
Adjust until the cross-hair image is in focus with minimal flare.
7. Adjust cross-hair pattern III, by adjusting the appropriate capscrew, see Figure 2-35 Screw Locations .
Adjust until the cross-hair image is in focus with minimal flare.
8. Repeat step 5, 6, and 7 as required until all 3 cross-hair patterns are in equal sharp focus. If the boresight is
acceptable, see step 11. If the boresight does not appear to be converging to an acceptable level of image
quality or if the lens will not focus over the correct range of throw distances, then the boresight requires
coarse adjustment, see step 9.
9. The original factory boresight can be recovered approximately by positioning the 3 setscrews, see Figure
2-35 Screw Locations . Position the setscrews flush with the front face of the lens mount plate and in
contact with the inner lens mount plate. Refer to Figure 2-36 . This may require adjusting both setscrews
and capscrews.
10. If further action is required. Repeat #2.
