5. Fine tune the focus of cross-hair pattern I by adjusting the appropriate cap screw, see
until the cross-hair image is in focus with minimal flare.
6. Adjust cross-hair pattern II, by adjusting the appropriate cap screw, see
hair image is in focus with minimal flare.
7. Adjust cross-hair pattern III, by adjusting the appropriate cap screw, see
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
2-16. Position the setscrews flush with the front face of the lens mount plate and in contact with the inner
lens mount plate, see below
10. If further action is required. Repeat #2.
11. Lock the setscrews, and re-check the boresight quality. Tighten the setscrew enough to ensure they will not
shift.
