2. Focus the image on cross-hair pattern I. Evaluate the focus on cross-hair image II and III. If all 3 images

are in focus, no further action is required. If boresight is required see step 3.

3. If boresight is required, refer to Figure 2-11 to understand how the adjustment screws on the lens mount

affect the corresponding cross-hairs on the test pattern. NOTE: The cap screw, (Figure 2-12) 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 2-12, 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 cap screw, see Figure 2-12. Adjust

until the cross-hair image is in focus with minimal flare.

6. Adjust cross-hair pattern II, by adjusting the appropriate cap screw, see Figure 2-12. Adjust until the cross-

hair image is in focus with minimal flare.

7. Adjust cross-hair pattern III, by adjusting the appropriate cap screw, see Figure 2-12. 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

2-12. 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 2-13 . This may require adjusting both setscrews and cap screws.

10. If further action is required. Repeat #2.
