hair image is in focus with minimal flare.
6. Adjust cross-hair pattern II, by adjusting the appropriate cap
focus with minimal flare.
7. Adjust cross-hair pattern III, by adjusting the appropriate cap screw. 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 approximately recovered, by positioning the 3 setscrews flush with
the front face of the lens mount plate, and in contact with the inner lens mount plate, see Figure 2-5
Position Setscrew Flush. This may require adjusting both setscrews and cap screws.
