You are now ready to perform a precision boresight alignment on the projector to achieve the best
possible uniform focus.
1. Back off each corner locking screw (1b, 2b, 3b, & 4b) - refer to Figure 1).
2. Observe which portion of the image is out of focus. For example if the
top left corner
of the image
is out of focus than you will need to adjust screw 3a until that point is correctly focused (see Grid
Test Patterrn at right).
3. Then, observe the
bottom right corner
of the image, which will now be out of focus. Adjust screw
1a to correctly focus that point.
NOTES: 1)
You will have to alternate adjustments to both screws
until both points come into focus (or fairly close to focus).
2)
Observe the opposite corners while
performing these adjustments as those opposite corners may come into focus as you are adjusting
the first 2 corners.
4. Adjust screw 2a until the
top right corner
is in focus.
5. Adjust screw 4a until the
bottom left corner
is in focus.
All four corners plus the center should now be correctly focused.
NOTE:
If the alignment process
causes the image to shift side-to-side or up and down by more than a few inches, re-center the image
using the lens cap with pinhole. Adjust the horizontal and vertical offsets to bring the image back to
the center. The image may have to be checked and re-centered a few times throughout this procedure.
BORESIGHT ALIGNMENT FOR FIXED LENS MOUNT DLV1400-DX AND
DLV1920-DX MODELS
When aligning boresight on the DLV model prjector, ensure the points below are observed:
• Use a 1.2:1 fixed lens.
• Focus the image as outlined in the steps above.
