Before you begin:
Properly position the projector relative to the screen (refer back to Section 2.3 Projector Position and
Mounting ).
Basic Optical Alignment Procedure
1. Display a test pattern appropriate for analyzing image focus and geometry, such as a single crosshair
centered across the image.
2. Course focus . Do a quick preliminary focus and (if available) zoom adjustment with the primary lens only.
Refer to Section 3.14 Working with the Lenses . Do not worry about consistency across the image at this
point, just center focus.
3. Center the image in the lens . Holding a piece of paper at the lens surface, adjust offsets as necessary until
the image on the paper is centered within the lens perimeter. A full white field works best for this.
4. Re-check side-to-side levelling . With a test pattern on screen, double-check projector leveling ( refer to
Section 2.3 Projector Position and Mounting ) so that the top edge of the image is parallel to the top edge
of the screen.
2.12 Boresight Adjustment
NOTES: 1)
Projector must be installed and powered up in its final location. Install the anamorphic lens if it will be
used at the site. 2) You will need a 3/16" Allen wrench. 3) Boresight may need slight adjustment after
installing a new lens.
To ensure proper offset for your site and
consistently good focus in all areas of the screen, a
primary lens must be installed and its lens mount
precisely adjusted in relation to internal optics as
described below. If desired, an anamorphic lens
can then be added to widen images for "scope"
displays. Once adjusted, boresight should remain
stable until the lens is replaced.
Refer to lens mount components illustrated in
Figure 2-48 for these adjustments.
2.12.1 Adjust Offset
NOTE:
Project an image using the primary lens only. The optional anamorphic lens, if present, can be mounted,
but swung aside.
Prior to boresight adjustment, offset the image as required so that the image is square on screen, but offset is
minimal. For best results, try to minimize offsets by "aiming" the projector lens at the center of the image.
Refer back to
Section 2.3 Projector Position and Mounting for offset ranges and method of adjustment.
