Boresight Adjustment; Adjust Offset - Christie Roadie HD+35K User Manual

Before you begin:
Properly position the projector relative to the screen (refer back to
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.

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

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.
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.
