Adjust Image Geometry And Optical Alignment - Christie Mirage WQ-L User Manual

Adjust Image Geometry and Optical Alignment

This initial optical alignment is the foundation for optimizing images on the screen, and must
be completed before final boresight adjustments. Only perform image alignment once the
projector is fully assembled and powered up in its final location.
Basic Optical Alignment
1. Press Test on the IR remote to display a test pattern.
It is recommended to use the Edge Blend or Grid test pattern.
2. Perform a quick preliminary focus and (if available) zoom adjustment with the primary lens. Do
not worry about consistency across the image at this point, just center focus. It is good practice
to have the zoom adjustment collar and the focus adjustment collar in the center of its range.
3. Hold a piece of paper at the lens surface, adjust offsets as necessary until the image is centered
within the lens perimeter. A full white field works best for this.
4. If necessary, 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. Aim the projector over slightly towards
the center of the screen, but use caution, as too much tilt will cause excessive keystone
distortion. Lens offset will not.
5. With the test pattern on screen, double-check projector leveling so the top edge of the image is
parallel to the top edge of the screen. Make sure the projector is positioned in the throw
distance range for the lens in use.
Folded Optics
In rear screen applications where space behind the projector is limited, a mirror may be used to
fold the optical path. The position of the projector and mirror must be accurately set — if
considering this type of installation contact Christie Customer Support for assistance.
