3.11 BASIC IMAGE ALIGNMENT

Only perform image alignment once the projector is fully assembled and powered up in its final
location. Basic image alignment ensures the image reflected from the DMDs is parallel to and well-
centered with the lens and screen. This initial optical alignment is the foundation for optimizing
images on the screen and must be completed before final boresight adjustments. Before beginning
ensure the CP2000-M/MR is properly positioned relative to the screen.

3.11.1 Basic Optical Alignment Procedure

1. Display a good test pattern appropriate for analyzing image focus and geometry, such as the
framing test pattern, showing the crosshair centered across the image.
2. Coarse focus: Do a quick preliminary focus and (if available) zoom adjustment with the primary
lens only. Do not worry about consistency across the image at this point, just center focus.
3. Center the image on the screen: If the projector is mounted off center to the screen axis, then
offset the lens as much as required, and/or aim the projector over slightly towards the center of the
screen. Use caution when doing so, too much tilt will cause excessive keystone distortion.
4. Re-check side-to-side leveling: With the framing pattern on screen, double-check projector
leveling so the top edge of the image is parallel to the top edge of the screen.
5. Throw Distance: Ensure the projector is positioned in the throw ratio range for the particular lens.

3.12 LENS MOUNT OFFSET AND BORESIGHT ALIGNMENT

To ensure proper offset 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. In some
applications a wide converter lens or anamorphic
lens can be used to accommodate changes
between flat and scope cinema displays. NOTES:
1) Projector must be fully assembled and powered
up in its final location. 2) Install the auxiliary
lens, if it will be used at the site. 3) A 3/16" and
5mm Allen® key are needed to make the required
adjustments (Figure 3-11).
