Section 2: Installation and Setup

ADJUST TOP/BOTTOM BORESIGHT

7. When left/right boresight is complete, focus the

image at the top edge of the screen (Figure 2-41).

If the bottom remains blurry while the top edge is

focused, refer back to Step 2, but place the paper

at the bottom of the screen to determine whether

the bottom of the image is focused in front of the

screen or behind the screen. If the bottom is well-

focused, proceed to Step 11.

8. Adjust the vertical boresight bolt (Figure 2-42)

using an Allen key to hold the bottom hex screw and another

to turn the adjustment bolt above it. Adjust as necessary to

direct or "aim" the lens toward the edge of the image, which

focused too close to the lens. When both top and bottom

appear equally blurry, re-focus at the top of the screen.

9. Adjust vertical offset to re-center the image on the screen.

10. Repeat Steps 8 and 9 until the top and bottom of screen are

both well-focused.

11. Although all sides of the image should now be in focus, the

center of the image will be slightly blurry at this point.

Refocus at center of image. The goal is good focus at center

and on all sides.

12. Adjust the "hold" screw to lock in place. Recheck boresight.

If present, swing the anamorphic lens in position in front of the

primary lens. It should magnify in the horizontal direction only,

stretching the image straight across the screen—this requires that its aperture (visible within the lens)

be vertically aligned with the screen. If the image appears skewed, loosen the locking ring on the

anamorphic lens and rotate the lens as necessary until the wide image is horizontal.

FOCUS PRIMARY LENS: With the anamorphic lens in place, re-focus the primary lens using focus knob.

The goal is good focus at center and on all sides.

FOCUS ANAMORPHIC LENS: If horizontal focus in the image needs improvement, focus the

anamorphic lens too—rotate its barrel as needed.
